'Bachelor' Ex Courtney How Do Ya Like Me Now?

Will you accept this pose?

It's obvious what Courtney Robertson has been doing since winning on "The Bachelor" (if that's really possible) and then getting dumped by Ben Flajnik -- working out.

The sexy 29-year-old showed off the amazing body that Ben's missing out on by wearing a pale green bikini on the beach in Los Angeles on Wednesday.

While she didn't get to walk down the aisle with Ben, Courtney will next appear on the wedding gown show "Say Yes to the Dress" ... but it's her sister who is the bride.

Always the bridesmaid ...

0-w4070fws

Mariann Gavelo has a huge ass. We're talking Kim Kardashian style HUUUUUUUGEEE ... and it was all out on display at a party in Hollywood last night.

Gavelo -- who appeared on "It's Always Sunny in Philadelphia" (the "Thunder Gun" episode) and in Will Ferrell's "Casa de Mi Padre" -- hit up the Maxim Hot 100 party with her badonk in tow.

Besides her dumper, Gavelo's a pretty petite chick, so we gotta ass -- is there ANY CHANCE that butt is real???

Discuss.

Rob Kardashian I'm Not a Big Loser ... Yet

Kim isn't the only Kardashian with a protruding belly.

Rob Kardashian has been pretty open about his weight struggles and continued on his quest to drop the extra pounds by rockin' some slimming black workout gear during a vigorous hike in Culver City on Wednesday.

In between trying to slim down, Rob is in the midst of a legal battle and recently pled not guilty to allegedly attacking a photographer and stealing her equipment for trying to take a shirtless photo of him.

Luckily, no one was harmed in the taking of this picture.

Jason Collins' Twin Brother Gets Straight to the Point

Telling apart newly out and proud NBA player Jason Collins from his identical twin brother Jarron Collins just got a whole lot easier.

Jason and Jarron were spotted leaving "Jimmy Kimmel Live" in Hollywood on Wednesday looking pretty similar as usual, except for one thing ... Jarron wore a shirt that highlighted a major difference between them.

As a joke, Kimmel gave Jarron the "I'm the Straight One" t-shirt during his interview on the TV show last night ... not that there's anything wrong with that.

Beyonce Pregnancy (Rumors) Never Looked This Good

With no signs of morning sickness dehydration or exhaustion, a healthier Beyonce once again took to the stage in Belgium on Wednesday.

One day after postponing the Belgium concert -- and further fueling the pregnancy rumors -- Bey didn't disappoint her legions of fans and brought her Mrs. Carter Show World Tour to Antwerp.

While she was decked out in a form fitting Ralph & Russo body suit, there's still no official word if Blue Ivy's mom is performing for two -- but she doesn't look it ... yet.

Turns out Beyonce is really pregnant by the way. So there you go.

Tiger Woods & Lindsey Vonn The Topless Boat Party

Tiger Woods lost the shirt off his back ... and this time his ex-wife Elin Nordegren had nothing to do with it.

The 37-year-old golf star aired out his man nipples and soaked up the sun by going shirtless on his yacht in Palm Beach on Tuesday.

While his fancy schmancy boat is called Solitude, Tiger spent the afternoon lounging and fishing with his two adorable kids and his sexy bikini-clad girlfriend Lindsey Vonn yesterday.

Although he's no stranger to being in the heat, hopefully Tiger used protection.

Tim McGraw Welcome to My Gun Show!

Even without his wife Faith Hill as his opening act, country hunk Tim McGraw still got upstaged at his own concert this weekend ... by his yoked body.

Rockin' his trademark cowboy hat and a tight white tank top, the 46-year-old singer showed off his ripped and buff tan biceps at the Atlanta stop of his Two Lanes of Freedom Tour on Sunday.

With such an amazing body of work, no one would ever argue that Tim has every right to bare arms.

O.J. Simpson If the Jumpsuit Don't Fit ...

O.J. Simpson is 100% GUILTY ... of putting on a bunch of weight behind bars.

Run, O.J. ... RUN!!

Hoda Kotb snatched the 79th spot on Maxim's Hot 100 -- and if you think that's a mistake you're either named Kathie Lee ... or you don't realize HoKo's been perfectly groomed for this honor.

Megan Fox Teenage Mutant Ninja Body Double!

Two Megan Foxes are better than one.

As if there wasn't enough gorgeousness around her, the perky 26-year-old former "Transformers" babe hung out with her less famous -- but still beautiful -- body double on the set of the "Teenage Mutant Ninja Turtles" movie in New York City on Tuesday.

In the Michael Bay produced flick, Meg plays TV reporter April O'Neil and will no doubt get to show off her amazing God-given talents ... and her acting chops too.

Cowabunga!

Adriana Lima The Bikini Heat Is On

For once in her life, Victoria's Secret supermodel Adriana Lima did not look smokin' hot in lingerie ... because she was too busy looking smokin' hot in a bikini.

The gorgeous 31-year-old mother of two showcased her flawless golden mamacita curves by modeling a bunch of tiny sexy two-piece swimsuits for a photo shoot in St. Barts on Wednesday.

While temperatures have been hovering around the mid 80s ... we hear there is a scorching Brazilian front (and back) moving across the Caribbean island.

Blake Lively Gets Thigh-High in NYC

Blake Lively is bootylicious.

Wearing an old school Jennifer Lopez diva hat, a '70s black mini-dress and a ridiculously hot pair of open-toed thigh-high boots, the happily married 25-year-old former "Gossip Girl" star strutted her gorgeous blonde and leggy stuff on the streets of New York City on Tuesday.

Apparently the high fashion walk off was all part of some magazine photo shoot, but who really cares about that ... the important thing is that she looks AMAZING!

Damn you, Ryan Reynolds! Damn you.

Zac Efron It's Gut Check Time

Zac Efron proved he's got game ... by flaunting his jacked-up rock hard chest on the set of his new flick.

With his shirt casually unbuttoned all the way, the toned 25-year-old stud played some basketball -- and showed off his ridiculously sculpted pecs and abs -- while filming "Townies" in L.A. on Tuesday.

Last month, Zac injured his right hand on set ... but everything appears to have healed quite beautifully.

Zac may be the one with the ball, but it's everyone else who has to worry about dribbling.

0-8qaxzf7c

Tara Reid is most definitely nursing a Wednesday morning hangover right now ... 'cause she hit the clubs so hard last night, she could BARELY STAND on her way out.

It's your classic ... "girl walks into a bar, girl chugs a bunch of liquor inside of the bar, girl gets so plowed she needs help leaving the bar" story.

The good news -- Tara didn't get behind the wheel ... she had a driver take her home.

Smart.
