Cameron Diaz appears to be giving ex Justin Timberlake some serious competition over who can make the most of their newfound single status. On the heels of her recent booty-shaking session with Djimon Hounsou (he's now dating Kimora Lee Simmons) and Hawaiian wave-riding respite with surfer Kelly Slater, the stubbornly brunette actress has been spied polishing the tonsils of model-actor Tyrese Gibson at Los Angeles hot spot Xenii, reports the New York Daily News. "They made out right in front of me on the dance floor," tattles a snitch. But a rep for Diaz, who also hit a pre-Oscar soiree with Gibson, insists to the paper that they're not dating. That will probably come as a relief to the woman reportedly carrying Tyrese's baby, who called the cops back in January after the two had an argument. Timberlake, for his part, has recently been spotted in the company of Scarlett Johansson and Jessica Biel.

Will Jennifer Aniston soon be sending out invitations to a blowout pity party? The New York Daily News claims her ex, Vince Vaughn, whom she broke up with late last year, climbed several steps down the classiness ladder as he "got flirty" with -- we can barely type the words -- Paris Hilton (no, Vince, no!) over the weekend during the World Poker Celebrity Invitational charity tournament at the Commerce Casino in California. The self-adoring, suspended license-driving starlet was snapped coyly waving in the general direction of the baggy eyed funnyman, who was seated across the table from her. But did Vince's unsuccessful attempt to style a "Sopranos"-esque slicked-back coif distract Paris, who has lately been hot and heavy again with sometime squeeze Stavros Niarchos? People says that after a stack of chips was shoved in front of her, she exclaimed in surprise, "I won?"

Is Samantha's slab of beefcake from "Sex and the City" robbing the cradle with Buffy's whiny little sister, who's an entire high school freshman younger than he is? Us Weekly says Jason Lewis, 35, enjoyed a date with Michelle Trachtenberg, 21, at Los Angeles' Chateau Marmont the night before the Oscars. "They just began hanging out," an insider tells the mag. The easy-on-the-eyes actor called it quits with Rosario Dawson late last year after two years of togetherness, while Trachtenberg was recently linked to Fallout Boy lothario Pete Wentz.

It's turning into a banner week for the tobacco lobby. Not only is Sienna Miller enthusing about her love for sucking down carcinogens in convenient stick form (see page 3), but Leonardo DiCaprio has also been caught stocking up on nicotine. People reports the environmentally minded A-lister popped into the food mart of a Los Angeles gas station to pick up a pack of smokes, a brief absence that seemed to make model-girlfriend Bar Refaeli's heart grow fonder. When Leo returned to the car, says the mag, the leggy looker leaned over and snuggled her head into his shoulder.
