Kim Kardashian and Reggie Bush prepped for a flight from Costa Rica yesterday following their fun weekend of bikinis and shirtless beach time. While Kim and Reggie were enjoying themselves on vacation, her sister Kourtney spent a few days filming Kourtney and Khloe Take Miami in Florida. She spent her afternoon running errands with Scott Disick and their son Mason, but Scott's dedicated daddy duty still doesn't have you convinced that he's that nice of a guy. Kourtney left Mason with Scott so she could pay a visit to the gym, and Kim was back to her own fitness routine as well, twittering fans for advice on how to prepare for her latest photo shoot.

Matthew McConaughey and Camila Alves brought their young kids Levi and Vida to LAX yesterday, where they hopped on a flight to NYC. The family is off on their latest adventure following Camila's red carpet stint at the Oscars - the Shear Genius host joined E!'s roster of correspondents reporting live from the scene. Levi chilled in his stroller as the family headed to their taxi at JFK airport, though little Vida stayed all covered up. Vida has been under the radar since Matthew and Camila released a few photos of her in January, but hopefully Levi can soon bring his little sister outside to join one of his adventures.

Newlyweds Jason Mesnick and Molly Malaney started yesterday in NYC with a stop by Live With Regis and Kelly, where they looked back on their recent wedding in California - ICYMI, check out the snaps from their beautiful, but rainy, ceremony! Jason and Molly were then off to catch a flight to LA, where they were spotted checking into their hotel after an outfit change. ABC aired a special episode dedicated to their recent nuptials last night, as both Jason and Molly keep showing off that just-married glow.

Practically all of the Gossip Girl gang was together in Manhattan yesterday to continue filming for their third season. Their show was finally back with a particularly steamy new episode on the CW last night after a long wait - check in for a recap of all the top WTF moments. The Upper East Siders also had their usual awesome tech gear, lux interiors, and fabulous fashions on display. It looks like there is a lot more to come from Blake Lively, Penn Badgley, Leighton Meester, Chace Crawford and also Michelle Trachtenberg. Michelle debuted a light-colored wig on set, as her character evidently gives Blake and Taylor Momsen a little more competition as the resident blondes.

Sienna Miller and her parents stood outside a hotel in sunny Soho, NYC, yesterday after apparently spending time together with Jude Law. The two have been keeping things fairly discreet, but also spent time with his mother and father in London at the end of February. Visits with both sets of parents in just a few weeks will do nothing to quiet the rumors that they're already looking toward giving engagement another shot. Still, their reunion isn't making everyone happy - it's causing Kate Moss some party invite stress.
