Tron's Olivia Wilde and the extremely sexy Jake Gyllenhaal are hooking up, according to online reports.

Reports claim the two stars were seen getting "touchy-feely" while hanging at Hollywood hot spot Chateau Marmont. Witnesses say although the two "weren't making a scene with PDA," there was definitely "flirting going on."

The eyewitness adds that at one point, Jake had Olivia's hand. What a hot visual!

Reps for both actors would not confirm nor deny the report.
