Even though the days are warming up we are still not quite in the summer season ... but it hasn't stopped these sexy stars from taking to social media to show they are ready to switch on the hot!

From poolside pics to babes just having some fun in the sun, there are so many celebs that are lookin' very ready for this next season!

Troy Aikman is absolutely jacked.

The 54-year-old "NFL on FOX" star hit the water for the weekend with a little boat trip in Florida with his former Dallas Cowboys coach Jimmy Johnson -- and showed everyone he's still carrying around a 6-pack under that shirt!

"What a weekend," Aikman posted on IG ... "Lots of laughs with great friends reminiscing our time together in Dallas and celebrating Jimmy Johnson."

Johnson was elected to the Pro Football Hall of Fame in early 2020 -- but the COVID pandemic delayed the induction ceremony.

Now, Jimmy is on track to get his bust in Canton in the Summer of 2021 -- and Troy is fired up for his longtime pal!

"We are all indebted to Coach for changing our lives. Next stop, Canton, Ohio! #hof #dallascowboys."

As for Aikman, the former QB was inducted into the HOF back in 2006.

Troy is a known health enthusiast -- he's always either working out in the gym, spinning or jogging around his neighborhood.

... and the hard work shows!!!

Lindsey Vonn busts her ass in the gym ... so why not show it off on the beach?!

The Olympic skiing legend posed for a series of bikini pics taken during a recent vacation with some friends ... and she looks incredible.

"You can judge me if you want, but I’ve been working hard in the gym and taking care of me," Vonn said ... "So I’m going to post some bikini pics because I’m proud of myself."

36-year-old Vonn is still a gym-aholic, despite retiring from competitive skiing in 2019.

She's a regular client of celebrity fitness guru Gunnar Peterson -- who commented on the photos ... saying, "Oh Hell yes you are!!! Work work workED!!! Posting mine next!"

In fact, Vonn is such a fitness junkie, she posted a video working out in a beachfront gym from the same trip ... saying, "Working out on vacation. Doesn’t get much better."

Her pal and fellow gym nut Dwayne "The Rock" Johnson called her out for the lack of plates on her squat rack!

It's good to be Michael B. Jordan!

Not only did the "Black Panther" star sit courtside when the Washington Wizards took on the Brooklyn Nets on Sunday ... but Russell Westbrook also gave him the jersey off his back!!

... and turns out, Russ has an 8-pack!

Brody's Wizards didn't get the win -- but they played well ... cutting a 14-point Nets lead down to 1 with just 3 minutes to go in the game.

Ultimately, the Nets emerged victorious in a 113 to 106 win -- thanks to 28 points from Kyrie Irving and 26 from James Harden.

Westbrook racked up 29 points, 13 rebounds and 13 assists -- and after the final buzzer ... he walked over to a masked-up Michael B. Jordan, dapped him up and gave him his jersey.

Russ also signed a personal message for the actor -- pretty cool moment.

Of course, Michael B. Jordan is also in pretty insane shape -- famously transforming his body for his roles in "Creed" and "Black Panther."

The Tampa Bay Buccaneers are facing off against the Kansas City Chiefs in Super Bowl LV on Sunday ... And it looks like both teams have already won in life!

With wives and girlfriends like this cheering you on, it's clear they've got some real good luck on their side this weekend!

From the Buccaneers we have Ndamukong Suh’s wife Katya Suh and Rob Gronkowski’s fianceé Camille Kostek... and from the Chiefs, we have Travis Kelce’s girlfriend Kayla Nicole.

Take a look through our gallery of Super Bowl LV WAGs to see all the other babes that will be rooting for their men this weekend!

Southern California actress Theresa Russell was in her early 40s when she took on the role of the head-turning widow Sandra Van Ryan -- who has a secret relationship with her daughter's high school counselor and her super dreamy "deckhand" -- in the skin-filled '90s film "Wild Things."

Theresa Russell shared the silver screen with some awesome actors including Denise Richards as her trust-lusting daughter, Kelly Van Ryan, Matt Dillon as the double-crossing counselor, Sam Lombardo ... and of course Bill Murray as the insurance-scamming lawyer, Ken Bowden.

Russell can also be spotted in "Spider-Man 3" and "Bad Timing."

Don't worry if you miss the New Year's Eve fireworks this year because the Kardashian/Jenner squad put on a serious show of their own over the last 12 months on social media with some of the most awe-inspiring selfies worthy of a round of applause.

While most of America is (hopefully) hunkering down and staying safe at home this holiday season there are some big-name stars that are still adventuring out of their homes and flying around the world on extravagant trips to share these scorching hot shots on the 'Gram.

Check out which celebs have booked lavish vacations and left the nest between Thanksgiving and Christmas of 2020 for some rest and relaxation ... then took to social media to post these smokin' selfies while the rest of us are sitting around the house.

Jennifer Lopez's new single drops Friday, but she's giving everyone still working before the holiday an early treat ... a NSFW photo to promote it.

J Lo shared the official cover art Wednesday for "In the Morning," and it's a pretty simple concept -- an all-nude, provocative shot of the singer in a clever pose ... one that covers enough to keep it clean for the censors.

In case you've lost track, because Lopez has been doing this sort of thing for so long ... that's a 51-year-old sex symbol doing her thing.

J Lo started turning up the heat last weekend with her AMAs performance with Maluma -- just as she did with Shakira during the Super Bowl Halftime Show. The 'Morning' cover art makes for a great bookend on her 2020.

The single starts streaming on Black Friday, and until then ... expect Lopez to continue aging like a fine wine and looking amazing at all hours of the day.

Sofia Richie is doing her best to give Scott Disick second thoughts ... she's looking sexy as hell on an island getaway.

Here's an idea of what Lord Disick is missing out on ... Sofia's slipping into tiny bikinis while on vacay in the Bahamas with her pops, Lionel Richie. If the crystal-clear water, blue skies and soft sand weren't enough to make Scott nostalgic ... Sofia's wardrobe, or lack thereof, oughta do the job.

It's a phenomenon we normally like to call post-breakup hotness, but let's call it like it is ... Sofia's always been smoking hot.

TMZ broke the stories ... Scott and Sofia officially broke up back in August after trying, but failing to work things out, and just last week he hit the beach with a new squeeze with famous parents -- Lisa Rinna and Harry Hamlin's 19-year-old daughter, Amelia Hamlin.

Your eyes and mind are not deceiving you ... Kim Kardashian is turning 40, and to celebrate, here are 40 of her best hot shots. Not that ya needed an excuse.

Yes, Kim K is celebrating the milestone bday Wednesday, which might have some of you wondering where in the hell the time goes. Thankfully, this gallery should help ease the sting of Father Time ... and just about anything else that's got ya down, really.

Check out the pics for the best possible hump day celebration most of us will muster today. It's a sweet stroll down memory lane that definitely includes Kim dressed to the nines.

BTW, a huge shout-out and big thank you to Paris Hilton for introducing Kim K to the rest of the world back in August 2006 as they sauntered into the Hyde nightclub in WeHo. Unforgettable moment ... even if you're not Tara Reid.

Lindsey Vonn came up with the perfect way to celebrate her birthday ... by throwing on her favorite bikinis and posting up on the beach in the Bahamas!!

The retired ski superstar and her closest friends took in all the sunny vibes for her 36th birthday ... but Vonn was the one handing out gifts via fire pics on her Instagram.

"36 and still in the mix!" Vonn said while sporting a sparkly brown 2-piece. "Thank you to everyone who sent me birthday wishes. 🙏🏻❤️"

The Olympian and NHL star hockey player P.K. Subban also posed for cute couple pics together ... with the 31-year-old saying he can't wait to "grow old" together.

As for the trip -- it looked fun as hell. Vonn and the crew went swimming with sharks, scuba diving and even caught their own lobster dinner!!

But, all vacations must come to an end ... and Vonn bookended the trip with one last shot on the beach.

"Until next time Bahamas... 👋🏻 #sadtoleave #nofilter."

Happy belated birthday, Lindsey ... we're already looking forward to next year's trip!!

Jared Goff's girlfriend Christen Harper is trying to take her modeling career to the next level by auditioning for the S.I. Swimsuit Edition ... and yeah, HIRE HER!!

Harper has been a model/actress for a while -- but she's been on a mission to follow the Camille Kostek blueprint to success.

Of course, Gronk's girlfriend -- a former New England Patriots cheerleader -- got a massive career boost when S.I. selected her for the Swimsuit Edition back in 2018. Her career is on fire!

Enter Harper, who's been dating L.A. Rams QB Jared Goff for a while -- and it's clear she thinks she could be the next big S.I. breakout star.

And, judging from her audition video, SHE'S RIGHT!

"I am SO excited to finally go after one of my wildest dreams," Harper said.

"[S.I. Swimsuit] has meant so much more than a magazine to me, it gave me the confidence to embrace who I am and ultimately chase my dreams."

Harper says multiple agencies told her she wouldn't be successful unless she could "just lose a few inches off my waist and that I wouldn’t be taken seriously outside of L.A. because of the size of my chest."

But "instead of shrinking myself down into an unrealistic standard for my own body, I chose to have faith that I was enough."

She ended with this message to the S.I., team -- "LET'S DO THIS!"

Peyton Manning has abs. LOTS OF ABS!!!!

Seriously -- look!!!

The 44-year-old ex-NFL star showed off his washboard stomach during a family beach trip to Miami this week ... and yeah, we're super impressed!!

He also tossed around the football while wading into the water and looked pretty good ... if you like 6'5", 230-pound quarterbacks with a laser-rocket arm.

The 2-time Super Bowl champ was never really known for his imposing physique during his playing days -- but it's pretty obvious he's still knocking out some crunches every now and then, despite being retired for the past 5 years.

Chicken parm ... it's not on the diet anymore?!

Manning hung up his cleats after the 2015 season -- when he led the Denver Broncos to victory over the Carolina Panthers in Super Bowl 50.

Next stop, Canton ... because Manning is finally eligible to be inducted into the Pro Football Hall of Fame, Class of 2021.

Kylie Jenner is flexing her political influence in a very impressive way ... turning your standard IG thirst trap into nearly 50,000 potential new registered voters!

TMZ's learned Kylie's smoke show bikini pics -- posted Monday -- are drawing huge traffic for Vote.org. She used the caption of those sexy shots to direct her nearly 200 million Instagram followers to hit up the site, and so many obeyed ... we're told it saw a whopping 1500% boost from traffic driven via Instagram.

There are more astronomical stats -- Vote.org got over an 80% increase in total users of its voter registration and verification tool from the prior day. That all translates to more than 48,000 users going to the site through Kylie's IG post ... and ya gotta figure that number's still rising.

By contrast ... only 2,900 users came to the registration verification tool via Instagram on Sunday out of 174k total users. So, there's clearly a very real Kylie effect working here.

Remember ... only around 138 million Americans -- out of 328 million -- voted in 2016. Now, more than 1 million have already cast ballots for this year's election ... the highest rate of early voting in U.S. history. For example, around this time 4 years ago, less than 10,000 people had voted.

Ya can't say Kylie hasn't done her part to get people to the polls. Aside from the pics this week ... she also implored fans back in June to NOT get distracted, and show up to the polls.
