Robert Downey Jr. is back in action as Iron Man for the third installment of the multi-million dollar Marvel franchise.

In the 30-second trailer, Iron Man leaps out of an exploding plane to rescue falling passengers. Intense!

Iron Man 3 hits theaters on May 3.

Hot mama!

Molly Sims is currently on vacation with some girlfriends in Mexico, and the former Sports Illustrated cover girl showed she's definitely regained her model physique by posing in a skimpy black bikini for an Instagram shot.

"Finally bikini ready & pulling out those @SI-Swimsuit poses, just in time for my bestie Lauren Kucarak's bday!" the blonde beauty captioned the picture.

The Kentucky native, who gave birth to son Brooks back in June, gained a whopping 65 pounds during her pregnancy, but has shed almost all the baby weight with a "no salt, no oil, protein-heavy' diet, Bikram yoga, and private training sessions with Tracy Anderson.

So was bouncing back from having a child as easy as it looks?

"I'm jealous [of women like Claire Danes]. I wish to God I could have done it that way. But my body just didn't. And I'm so happy I have an amazing, happy, healthy, gorgeous, Buddha-like son, but I wish it would have been easier. I tell my husband, it made me depressed a little," she recently confessed to Us Weekly.

We think you look simply stunning Miss Sims!

So great to see Kelly Rowland, Beyonce and Michelle Williams of Destiny's Child back together!

The sexy threesome belted out their hit song "Bootylicious" during an amazing Super Bowl Half Time performance. The girls even helped Beyonce perform "Single Ladies." Talk about perfection!



Following her flawless show, the 31-year-old songstress got a backstage hug from hubby Jay-Z.

Over the weekend on NFL's Super Bowl Live show, Beyonce said the following about Jay-Z: "My husband is incredible .. .He's so supportive."

Aww! Blue Ivy's mom also announced plans for the Mrs. Carter Show World Tour with the incredibly sexy video below. We can't wait to see her rock the stage again!

Britney Spears took advantage of another beautiful day in L.A. on Sunday as she and her sons paid a visit to the veterinarian's office in Westlake Village.

The 31-year-old singer has been doing well since her split with ex-fiance Jason Trawick but won't be the next celebrity to take up a residency in Las Vegas according to recent reports as a rep for Caesar's Palace said the venue is projected to be packed throughout 2013.

Looks like she'll have more time to work on that new album of hers!

She won't some pregnancy slow her down!

Kim Kardashian showed she won't be some dormant mom-to-be on Sunday as she hit the streets of Los Angeles to run some errands.

The 32-year-old reality star, who donned workout gear for the day, was more shapely than usual as her pregnancy pounds begin to show but she's been on a mission to keep her weight in check with the help of famed trainer Tracy Anderson. Way to stay on track girl!

Does she have a bun in the oven?

On Sunday, a covered up Fergie didn't forget anything for her Super Bowl shindig as she made a quick stop a Whole Foods in L.A. before the big game.

The Black Eyes Peas singer has been keeping it relatively relaxed during her group's hiatus yet still manages to keep busy and enjoy the leisure time. Her newfound freedom has allowed her to embark on other activities, which could possibly explain her voluptuous figure.

We're guessing her hubby Josh Duhamel is enjoying her time off as well!

Hilary Duff is always in a good mood when we snap her picture, but after a few sips of coffee, she looked like she was on cloud nine!

We spotted the former Disney star grabbing coffee with a pal over the weekend, and from taking son Luca to a petting zoo to filming a guest spot on Raising Hope, she's had quite a busy week!

The other day she tweeted, "Long day on set. Just breaking for lunch. I think I feel a sweet tooth attack coming on. Ohh noooo!" Given how disciplined she's been about hitting the gym since giving birth, we're sure it wouldn't be the end of the world if she indulged in something sugary ... she deserves it!

Beyonce rocked the stage at Super Bowl XLVII in New Orleans, performing some of her new tunes and reuniting with Destiny's Child for some oldies, like everyone's fav, "Bootylicious."
