Summer

Carrie Underwood slipped into her best neon pink and soaked up some rays in Mexico.

Carrie and her hubby, NHL star Mike Fisher, are vacationing in Cabo. Check out the pics ... Carrie couldn't look hotter and brighter.

Justin Bieber's new gal pal has a striking resemblance ... to one Selena Gomez.

The Biebs was chillin' with Puerto Rican model Alexandra Rodriguez on a yacht down in Miami. Hard to tell ... but she might be wearing his swim trunks ... which doesn't do her any justice. Check out the pics below ... Alexandra can wear the hell out of a red bikini.

Justin definitely knows how to ride.

If 6'6'' 265-pound Rob Gronkowski shows up to your house, you better have plenty of extra taco meat.

Luckily for Jeff Ballard -- former rep for Charlie Sheen, Zac Efron and Johnny Depp -- he was well-stocked when he got a text from a buddy asking if he could bring a "random" +1 to taco night.

Gronk was in town and decided to swing by the Sherman Oaks backyard party with a mutual friend of Ballard's. Rob crushed 15 carne asada and chicken tacos with the works. We're told normal humans only threw down 2 or 3.

Gronk stayed for almost two hours, throwing a football around with the guests and chilling poolside. Most shockingly, we're told Rob rejected Coronas and opted for water.

Demi Lovato made sure the rays caught all her good parts while lounging poolside in Miami.

We'd say she looked bent out of shape over her recent breakup with longtime BF Wilmer Valderrama, but these pics prove otherwise.

LeBron James, Dwyane Wade and Chris Paul are all partying on a yacht off the coast of Spain -- and having a BLAST!

Kyrie Irving says allegations that his yacht party was a "No Black Girls Allowed" event is complete BS -- calling the rumors complete "nonsense."

The Cleveland Cavs star came under fire from social media trolls who saw the footage of Kyrie on a boat with a bunch of women ... many of whom were white.

Now, Kyrie is firing back at the critics -- saying, "I'd never think I would have to address something as ridiculous as a yacht party, but I wasn't raised to discriminate against any race let alone any race of women, especially my own."

"I was raised by the black women in my family and for me to be connected to some nonsense like a 'No black girls allowed' party is embarrassing and an inaccurate portrayal of who and what I represent as man."

Irving apologized to the people who were offended without knowing the facts -- but says, "that story has no truth to it and I wanted to clear the air on all of this B.S."

Beyonce's working with sour accessories in Hawaii ... call it a sweet marketing ploy.

Bey and Jay Z are currently enjoying paradise beachside. Check out the pics ... Beyonce traded diamonds for a lemon rope. She's definitely got "Lemonade" on her mind ... in case that crown wasn't a dead giveaway.

Kesha slipped into a little black bikini for a desert vacay with her longtime boyfriend.

The singer was poolside in Palm Springs over the weekend. She and writer Brad Ashenfelter did their best to stay cool in the triple digit temperatures.

Check out the gallery to see the awesome bonus they got ... from a masseuse!

Trey Songz got tired of watching Drake have all the fun, and put together a rival poolside turn up.

The singer spent $25k to rent a MASSIVE 23,000 square foot home Sunday in McLean, Virginia -- just outside DC -- and the guest list was 700 deep, including Kevin Durant and a bunch of Washington Redskins players.

Check out this video from inside the event -- Trey was nice enough to introduce a chick to the pool. He teamed up with DC promoter Bobby Patterson to pull it off and dropped another $50k just for the open bar. Food? A mere $8k.

Despite hiring 30 security guards, chick fights still broke out. See? Just like Drake's pool party.

It was sunny and 75 in Los Angeles Tuesday ... so UFC superstar Paige VanZant hit the beach.

Model pose? Check.

Bathing suit handstand? Check.

Butt selfie? Check and mate.

BTW, don't be jealous of the weather ... it's only supposed to be sunny and 69 today.

Jessica Alba's amazing body, and bank account, were on full display in Cancun.

Cash Warren -- already the luckiest guy on Earth -- just got way luckier.

The NY Jets are one step closer to being the hottest team in the NFL -- all thanks to Denise Richards.

The 44-year-old rocked a tiny Gang Green bikini out in San Diego this week ... begging the question -- since when is she a Jets fan?!
