Jessica Simpson has been quite the travelin gal lately.

After attending the grand opening of the Palms Place in Las Vegas, with her pregnant sister Ashlee, Jessica popped up at the airport in San Diego, as she and on-again boyfriend, Tony Romo, prepared for a flight abroad.

Prior to Vegas and San Diego, Jessica was all smiles when she arrived at LAX with BFF/hairstylist Ken Paves, as they returned from a trip down south to Nashville (to work on her country album) and to Dallas (to visit her man). Jessica is turning into quite the Southern Belle, showing off her Texas pride in a Cowboy hat.

But, the jet-setting doesn’t stop here - prior to Jess’s quick trip to the South, she boarded a private plane, with her dog Daisy, of course, for a family vacay, with mom and dad, following Ashlee and Pete’s nuptials. The Simpsons jetted off to Cabo San Lucas, where they rented a house, and engaged in some post-wedding R&R. Jess was seen rocking a Dallas Cowboy hat while drinking cocktails in Cabo, as well as sunning by the pool everyday with her mom Tina.

KFed parties in Vegas for his 30th birthday bash. His ex Shar Jackson was in attendance, but no sign of Britney, thank god. It’s hard to believe that he [Kevin] is considered to be the responsible parent, he’s always in Vegas, always hosting and partying at any and every hotel on the strip.

Audrina becomes a Pussycat Doll for a night in Vegas. Looks like she’s lovin’ her 15 minutes of fame, literally, livin’ up every second of it - and she should, just like her other “Hills” co-stars have been doing [on the covers of Us Weekly] week after week.
