According to the stars themselves, the rumors are just that – rumors.
"They are rumors," Ashley told Access Hollywood at the Los Angeles Lakers' victory party on Thursday night. "We met at a surfing event and I haven't seen him since."
According to a previous People report, the two met last Friday at Oakley's "Learn To Ride" surf event, where the pair "got super cozy all weekend."
But Adrian seconded Ashley's story, denying that the two were a couple.
"You said it yourself, rumors," he told Access. "Yeah, come on — can't get snapped with anybody without them saying something."
However, there's one star Adrian would like to hook up with – asked who he'd like to see cameo on "Entourage," he went with "Iron Man" star Robert Downey Jr.
"There's so many," he added.
The November 20 release date of Ashley's "New Moon" is still months away, but Adrian fans can catch his return to HBO on July 14, when the sixth season of "Entourage" premieres.
