Spending this weekend together, Ashley Greene and Adrian Grenier have ignited speculation that they are a new item. The twosome's first meeting occurred at the welcome dinner at Oakley's "Learn to Ride" surf weekend held on Friday, June 12 in Santa Barbara, California. Since that time, the twosome wasted no time to hit it off.

A source tells People to have witnessed the alleged lovers dancing to music by Kelley James during the dinner. "[They] really had a great time," says the source. The next day, the "Twilight" beauty and Adrian spent some quality time together again. They reportedly talked and took surf lessons.

Later that night, both of them met at a barbeque held at El Capitan Ranch. There, they "were flirting and dancing close all night long," claims the source. "They held nothing back dancing - it was pretty intense."

Though neither Ashley nor Adrian has acknowledged the dating rumors, the source insists, "[They] got super cozy all weekend. They were very cute. They were hanging out nonstop and they only met Friday. They spent the whole time together - surfed together - everything."
