(news.sawf.org) - The 32-year-old Crash star - who split from wife of seven years Reese Witherspoon last October - recently met the 22-year-old singer at hip Los Angeles nightclub Les Deux before spending the night at Ashlee's $6 million home, it has been claimed.
A source told Australia's New Weekly magazine: "When Ryan and his friends arrived they were shown to the only table with any space left - where Ashlee and her friends were sitting.
"He couldn't keep his eyes off her in her very figure hugging little black dress. They seemed very into each other. Ashlee was really excited. You could tell she had a huge crush on him." After flirting for hours, onlookers claim the couple disappeared to a private area upstairs, called The Library, at around 2am. The source added: "They were up there for over an hour and came back looking disheveled. We knew something went on.
"They took separate cars and met at her place. He spent the night! Ashlee is keeping quiet and just said how hot he was. They really hit it off. I think they will hook up again." Ryan's representative has denied the allegations.
He said: "Ryan does not know Ashlee aside from a brief introduction. He went out with his friends and left with his friends." The Cruel Intentions star has two children with Reese Witherspoon - seven-year-old daughter Ava and three-year-old son Deacon. She is allegedly dating her Rendition co-star Jake Gyllenhaal.
