Are Cameron Diaz and Gerard Butler Getting Serious?

Are things heating up between Cameron Diaz and Scottish actor Gerard Butler? Just as news hit that the A-list pair have been seen canoodling at various Hollywood hotspots, new reports are surfacing that Cameron is introducing Gerard to her friends. The couple were spotted at the Chateau Marmont, on a double date with Reese Witherspoon and Jake Gyllenhaal. "They arrived at 12:30 a.m. and grabbed a table on the patio," an eyewitness revealed to Life & Style. "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."

We know it's a big step for Cameron to introduce her lovers to her friends, but we'll only believe things are getting truly serious between these two when we spot them out with BFF Drew Barrymore and her boyfriend Justin Long. Still, they've got a pretty good start at being one of Hollywood's most beautiful couples.
