The 'House M.D.' star prompts another dating rumor after she was seen getting 'touchy-feely' with the 'Source Code' actor during a recent night out at Chateau Marmont.Olivia Wilde sparked a new dating alert with another Hollywood hunk. This time around, the actress who plays Dr. Remy "Thirteen" Hadley on Fox's drama "House M.D." allegedly shared a flirty night with actor Jake Gyllenhaal at Chateau Marmont in West Hollywood.

Words are, Olivia stole the attention of the ex-boyfriend of Reese Witherspoon when he was enjoying his night out with a group of pals. An onlooker told PEOPLE that the two Hollywood stars were "very flirty" and "acting 'touchy-feely'."

"At one point, he had his hand on hers," so said the witness. Still, it was noted that the twosome weren't overly affectionate, especially on Olivia's part. The inside source dished on "Olivia was very cool and wasn't fawning over Jake but seemed to like the attention he was giving her."

Olivia and Jake went their separate ways by the end of the night. While the reported flirting sparked rumors over the two's relationship, a representative from the "Tron Legacy" actress quickly put on the brake by stressing, "They're just friends."

Olivia has been hit with numerous dating rumors ever since she split from husband Tao Ruspoli. She has been linked romantically to the likes of Justin Timberlake and Bradley Cooper among others, but insisted in a recent interview that the dating rumors were not true.

"I am single. I think that now people are curious so if I am with a friend they think he is my boyfriend," she insisted. "I have a lot of guy friends, but they are only friends. I find it hilarious. I don't know why they think that I could have the energy to be dating so many people."
