We caught Cameron Diaz and Gerard Butler out on a date at the Chateau Marmont last Friday, but now Life & Style are reporting that the new couple were there with Reese and Jake!

L&S reports that an eyewitness told them "They [all] arrived at 12:30 a.m. and grabbed a table on the patio ... Cam snuggled up to Gerard and rested her head on his shoulder. Jake and Reese were really cute together, too -- joking a lot and just very comfortable with each other.

The mag says Cameron was the life of the party, making everyone laugh. They report that Gerard and Jake didn't talk to each other too much; and Cam and Gerard held hands under the table.

Reese and Jake left at 3 am, according to L&S, and the time on our cameras read 3:35 when we snapped CamBut.
