Weekend PIX: Lil Jon, Brandy, Snoop, Legend, Ray J and Kristin

Everyone was supposedly celebrating their birthdays this weekend at the clubs. Hmm. Let's see ...

I love this photo of Lil Jon, caught eating birthday cake at Strip House. Because of his awesome outfit, it looks like one of those old gangster photos from the 1920s. Sort of. His birthday isn’t till Jan. 27. Courtesy photo by Andrea Tunbridge/Andrea Tunbridge Photography.

Ray J and sister Brandy did up club Pure Saturday night with 30 friends, including his girlfriend Pena, plus Snoop Dogg, then Ray J sang a few of his singles, and Brandy led a chorus of "Happy Birthday" to him. Floyd Mayweather took 15 people to the party later. Ray J’s birthday is today. Courtesy photos by David Becker of Wire Image.

Ray J then did up more birthday celebrating on Sunday night at club Vanity till 4 a.m., closing the place down. Courtesy photo by Hew Burney.

“The Hills’” Kristin Cavallari did her birthday celebration at club Bank on Saturday night. Her birthday was two weeks ago on Jan. 5. Courtesy photo by Denise Truscello/WireImage.

And John Legend celebrated his birthday with girlfriend Chrissy Teigen at club Haze Saturday. His birthday was three weeks ago on Dec. 28 — last year. Courtesy photos by Denise Truscello/WireImage.
