Post-split peace talks?

Heads turned at L.A.'s Chateau Marmont at 11 p.m. Jan. 28, when exes Ryan Reynolds and Scarlett Johansson, who filed for divorce Dec. 23, got drinks on the patio and chatted for an hour.

Johansson, 26, did most of the talking in what appeared to be a rollercoaster conversation. She would at some points smile, then appear to fight back tears. Turns out it wasn't just a nightcap, either.

The pair also dined at L.A.'s Little Door earlier that night and "seemed comfortable," says a source.

So are they back on? "There are no plans to reconcile, but they’re still friends," adds an insider. (Reynolds, 34, spent a flirty New Year's Eve with Sandra Bullock; a rep for Johansson recently denied reports that she is dating Saturday Night Live's Jason Sudeikis.)

Says another pal of the former couple, "They have divorce details to work out, and they'd rather do it face-to-face than in some office."
