Tying The Knot

Serena Williams is 5 months pregnant, and even though she just announced it to the world ... she's barely showing.

She just posted a profile pic of herself in a one-piece swimsuit and captioned it, "20 weeks."

Sources connected to Serena tell us it's exactly what it looks like ... she IS pregnant, even though her reps aren't confirming yet.

Serena got engaged to Reddit co-founder Alexis Ohanian back in December. If ya do the math, it kinda adds up. Looks like they might be celebrating with a vacay.

Congrats to Serena and Alexis -- and also to every other female tennis player! Your chances of winning a tournament this year just went up.

Kid Rock doesn't kid around when it comes to locking down his longtime gf ... we got the first shots of the diamond ring he put on Audrey Berry when he popped the question.

Sources close to the couple confirm they got engaged earlier this year, but rumors started swirling when Audrey was seen rocking this ring on her left hand during Kid's fan cruise a couple weeks ago.

No question, Audrey looked totally charmed by her rock ... she couldn't stop smiling and staring at it.

Audrey and Kid have been linked together for nearly a decade. This will be his second marriage. He famously married Pamela Anderson in 2006.

Sam Hunt and his new wife, Hannah Lee Fowler, are doing that thing newlyweds do -- heading out for their honeymoon, and looks like she's getting a long one.

The Hunts were at Atlanta's Hartsfield-Jackson airport Monday with two giant suitcases, so we're guessing they've got more than a week planned. They were both sporting their rings, but no clear shot of Hannah's. Let's be honest ... no one cares what the guy's looks like.

No word where they're headed, but we're sure it'll be sickeningly beautiful wherever they land.

They got hitched Saturday in a small wedding, in celebdom anyway, only about 150 of their closest friends and family attended.

Green Bay Packers receiver Randall Cobb is officially a married man ... and he had a little help from a couple superstar groomsmen -- Aaron Rodgers and Jordy Nelson.

The Pro Bowler married his longtime girlfriend, Aiyda Ghahramani, in New York over the weekend ... with his Packer teammates and other pros like Prince Amukamara in attendance at The Pierre hotel.

250 of the couple's closest friends and family attended the ceremony and celebrated with a reception, according to The Knot.

Something worth noting: Aiyda and Olivia Munn became close friends while she dated Rodgers (they even spent this past Christmas together) ... but it's unclear if she was at the wedding and we can't find any photos of her there.

Sam Hunt and Hannah Lee Fowler celebrated their wedding at what looks like a pretty awesome venue in Georgia.

Sam and Hannah had the reception at a place called In the Woods in Rockmart, GA. It's one stop shopping for folks who get hitched, but they didn't get married there. The nuptials went down in nearby Cedartown at a Methodist church.

We're told just shy of 150 folks attended the wedding and reception, with no celebs to speak of.

Check out the venue ... pretty sweet.

Sam Hunt will be a married man Saturday after he ties the knot with fiancee Hannah Lee Fowler in his Georgia hometown ... TMZ has learned.

Sources involved in the wedding tell us ... the ceremony will go down in Cedartown, Georgia and it will be a small affair -- close family and friends only.

That doesn't mean Sam's doing it on the cheap ... quite the opposite. We're told renowned Nashville bridal designer Olia Zavozina is all over the wardrobe ... she's designing duds for the men and a super expensive wedding dress for Hannah. She's also dressing Hannah's bridesmaids.

She recently designed Hunt's outfit for the ACM Awards.

The ceremony and reception will be videotaped, but we're told Sam and Hannah will NOT sell their wedding photos to any of the mags.

The couple got engaged in January ... so it's a pretty quick turnaround.

Wedding season has begun!

IT'S TRUE ... apparently!

WWE superstars Dean Ambrose and Renee Young tied the knot in real life ... so says Renee!

Rumors had been swirling ever since fans noticed the wrestlers were each sporting rings on their wedding fingers ... even though they never referenced the jewelry on TV.

But Wednesday morning, Young seemingly put the whole thing to bed saying, "Marriage is nice. Thanks for all the love."

The two have been dating in real life for roughly 3 years.

So ... MAZEL!!

Khloe Kardashian says she's DEFINITELY down to marry Tristan Thompson ... even though he hasn't exactly proposed yet.

If anyone had doubts 'Bachelor' star Nick Viall and fiancee Vanessa Grimaldi were the real deal this footage from Sunday's "Dancing with the Stars" rehearsal should put those to bed.

Nick's dancing the rhumba to Ed Sheeran's "Shape of You" Monday night and looks like Vanessa's gonna join him for part of it.

He pulls her out of her seat and, at least during rehearsals, he had a really hard time letting her go ... especially once their lips locked.

Linda McMahon was in the hot seat during a hearing in D.C. on Wednesday ... when a Republican congressman called her out and demanded answers ... about John Cena's engagement.

The congressman pushing the issue is Rod Blum of Iowa -- who used his 45 seconds of floor time ask Linda about the big story from WrestleMania 33 ... Cena's proposal to Nikki Bella.

The question got some chuckles in the room ... but one person who wasn't havin' it was Linda.

The head of the Small Business Administration smiled ... but shut Blum down with the efficiency of a patented John Cena STFU.

It's only April ... but bikini season is officially underway ... so sayeth Johnny Manziel's smokin' hot fiancee, Bre Tiesi.

Bre did a little bikini modeling at Posh Shop in L.A. -- showing off her insane physique.

Johnny and Bre got engaged back in March and no wedding date has been set -- but here's one lady who clearly doesn't need any of those bridal boot camps.

Martin Lawrence didn't cut corners on his engagement to Roberta Moradfar -- instead he plunked down about a half mil for her rock .... TMZ has learned.

Sources connected to the couple tell us Martin worked for months with Iconic Jewels Beverly Hills to create the custom 5 carat emerald cut engagement ring. He added another carat for the band alone, which has Martin and Roberta's initials spelled out in diamonds.

Martin popped the question Friday night to Roberta, a nurse practitioner ... just a few hours after the ring was delivered to his home.

This will be his third marriage, but he's clearly not gun-shy.

Mazel.

John Cena and Nikki Bella started down the road to marriage when they were both doped up for surgeries.

The freshly engaged WWE superstars went on "Today" and revealed a cool story about what they said to each other while getting wheeled into operating rooms.

John says Nikki shoulda known a proposal was coming because he flat-out told her, "You know someday I'm going to marry you?"

John Cena busted out a ring IN THE RING ... popping the question to fellow WWE superstar Nikki Bella -- and like her brother-in-law, Daniel Bryan, she said, "YES! YES! YES!"

Cena whipped out the massive Tiffany's diamond after he and Nikki beat up The Miz and Maryse in a co-ed tag team match at WrestleMania 33.

Here's the thing ... Cena didn't use her "ring name" -- he proposed with her real name, "Stephanie Nicole Garcia-Colace" -- leading most people to think the proposal was real and not a scripted bit.

John and Nikki have been dating in real life since 2012.

After the event, Cena tweeted about the proposal.

Robert Blake and Pamela Hudak not only took out a marriage license earlier this month ... they appear to be married.

We got the two hand in hand up in Beverly Glen Sunday and our photog congratulated them on their "marriage." Robert acknowledged with a nod.

A nod, however, is all we got.

Robert was acquitted in 2005 the murder of his second wife, Bonnie Lee Bakley.

Colton Haynes is on the fast-track ... a quickie wedding followed real quick by some bambinos.

The "Teen Wolf" star was all smiles at LAX Thursday after getting engaged to Jeff Leatham in Cabo.

He knows at least one song they'll play at the wedding.
