Harry Styles & Robert Pattinson Party, Drink Together in LA: One Direction and 'Twilight' Heartthrobs Bond Over Ex Girlfriends Taylor Swift, Kristen Stewart?

Several Twitter fans confirm that "Twilight" heartthrob Robert Pattinson and One Direction crooner Harry Styles were spotted hanging out together in LA earlier this week. Apparently, the two Hollywood stars grabbed a drink together at LA's infamous celebrity hot-spot, the Chateau Marmont. Wonder what they talked about... perhaps ex-girlfriends Kristen Stewart and Taylor Swift.

Check out these fan tweets:

@1DUpdaterGirls tweeted on Sept.11, "Harry Styles was at the Chateau Marrmont Hotel!!! With Robert Pattinson having a drink and talking. They argued over who was paying."

@Socialite_LA tweeted on Sept. 11, "So all that drama outside Chateau Marmont was cuz Harry Styles & Robert Pattinson were just there spotted together #WestHollywood #WhoCares."

Funny... the British pals allegedly grabbed some drinks, but Styles is only 19...

Anyway, it looks like the duo had a good, relaxing time on their "bro" hang-out. No Swift or K-Stew drama included!

Rumors suggest that R-Patz is "playing the field" as a newly-single man, while the 1D cutie is romancing model Cara Delevingne. One Look magazine insider reveals, "They have great chemistry. Sure, they've always agreed to keep things super casual and private because of their crazy worlds, but Harry genuinely likes Cara a lot - he has done ever since they met three years ago."
