Brad Pitt kicked off the New Year with a week of holiday fun with Angelina Jolie and his parents. But according to Us Weekly's Katrina Szish, don't look for a trip down the aisle or a bundle of joy anywhere in Brangelina's near future.

"Over the holidays [Brad's parents] went to visit Brad and Angelina, specifically to get to know Angelina better," Szish told us. "There have been reports that she has been taking pre-natal vitamins and that she's even been spotted with something that looks like a little belly bump, except according to Angelina, she is not ready to have a baby yet so close to adopting Zahara."

Meanwhile, Brad's ex, Jennifer Aniston, and Vince Vaughn enjoyed a cozy afternoon together in Las Vegas Monday. The couple was apparently in Sin City to celebrate 2006, and according to the Las Vegas Review Journal, they rang in the New Year at Mandalay Bay's Forty Deuce.

Reports say Jen actually took the stage at the notorious burlesque bar Sunday, performing a special dance for Vince.

Nicollette Sheridan is spending her holiday season on the shores of Hawaii, but the "Desperate" diva may be celebrating more than just the New Year. New pictures show a rock on the "Housewife's" ring finger, and it looks an awful lot like an engagement ring.

Sheridan has been spending plenty of time with former flame Michael Bolton recently. But before anyone starts ringing the Wisteria Lane wedding bells, "Extra" talked to Sheridan's reps this morning, and they told us she is not engaged.

Also enjoying some time in Hawaii is Hollywood's favorite bikini-clad actress Jessica Alba. After a breakout year in 2005, the Hollywood stunner started 2006 with a little rest and relaxation alongside boyfriend Cash Warren, whom she met while shooting "The Fantastic Four" in Vancouver.
