Kellan Lutz won't kiss and tell when it comes to AnnaLynne McCord.
After a summer fling that included dinners in Montauk, New York, as well as a secret rendezvous in San Diego, Us Weekly has reported that they split in mid-October -- only to be photographed smooching in Los Angeles Oct. 26.
Asked Monday on Ryan Seacrest's KIIS-FM radio show if they're still an item, Lutz, 24, clammed up.
"Oh. No. Never have been," he said. "I've known her for six years, and we met again on the set [of 90210], but we shot Abercrombie [catalogs] way back in the day."
He said "she's single, and I'm very much single."
When it comes to his love life, "I don't really think about who I want to date," Lutz said. "I kind of fall into situations, and then I'm like 'Oh, I'm dating you now.'"
Thoughts on costar Kristen Stewart?
"She's awesome," he says. "She's very independent."
Alas, Robert Pattinson has nothing to worry about.
"I think she's too independent for my blood," Lutz said of Stewart, 19. "She's so spicy."
Still, he said that he "would love to kiss her" on screen and that in New Moon (out Nov. 20) and Eclipse, Twilight's third installment, he has been lucky to have more screen time with her.
Said Lutz, "It's cool to finally have good scenes with her because you can hang out with people and have good relationships."
