Reese Witherspoon and Jake Gyllenhaal keep us guessing.

While the two A-listers have kept mum on reports about their friendship turning into romance when they shot the upcoming thriller Rendition, I’m told they appeared to be way into each other last night.

The maybe-couple were at Carrie Fisher’s L.A.-area home for a party toasting singer Rufus Wainwright, who earlier in the evening had appeared at the Hollywood Bowl performing his almost exact replica of Judy Garland’s legendary 1961 concert at Carnegie Hall.

“Jake and Reese were sitting by the fire all night, talking,” a fellow party guest tells me. “Everyone was talking, laughing and celebrating Rufus, but they were deep, deep in conversation. It was like there was no one else in the world.”

So, who else was in attendance? Among the boldfaced names in the crowd were James Blunt, Dita von Teese, David Geffen, Barry Diller, Fisher’s ex and CAA honcho Bryan Lourd, Jeanne Tripplehorn, Kate Pierson of the B-52's and Fisher’s mom, Debbie Reynolds.

Reps for Gyllenhaal and Witherspoon did not comment.
