'Twilight' Romance Update: Which Of The Stars Are Still Single?

Ashley Greene and Adrian GrenierWhispers of a possible new Hollywood couple began last week when "Twilight" actress Ashley Greene was spotted on a maybe-date in L.A. with "Entourage" star Adrian Grenier. But, the duo now want to assure everyone: They are not dating.

"I have only met him once. But he's very smart. We actually started talking about environmental stuff. He's a very go-green guy," Ashley told People. "I think he's a really sweet guy." But, what does she think of everyone saying how cute they'd be together? "God, that's what I keep hearing!"

Well, it seems her rumored beau is sticking to the same story. When he was asked about the romance rumors, he told Extra, "We were at a surfing lesson. Oakley was doing a surfing event and she was there. We did share a dance like many people did and I didn't have sex with them either. She's a great girl and we're just friends for now."

Speaking of "just friends," Selena Gomez is still mum about reports that she's dating Taylor Lautner. And even though she recently insisted she's single, in a special edition of People (out last week), she didn't really deny the werewolf romance (or, for that matter, confirm it either). "We're good friends and we're shooting projects in Vancouver," she said. "I love meeting new people and I love being friends with people in the business." She later added, "I can't really say," when asked if there was more to the friendship.

One Forks vampire not shy to put his love on display is Kellan Lutz, who was spotted over the weekend at a new NYC restaurant with his girlfriend, "90210" star AnnaLynne McCord. Well, it's nice to see someone owing up to their romance in public!

Who else do you think Ashley Greene should date now that we know she's not together with Vinnie Chase, er, we mean Adrian Grenier?
