The guys came out in support of their guy Monday night: Jason Bateman and True Blood star Joe Manganiello attended the party for pal Ryan Reynolds' Details cover.

After the event at Dominick's in West Hollywood, hunk-of-man-meat Manganiello was quite the gentleman; he opened the car door for his girlfriend, model Audra Marie. See all the chivalrous pics in our gallery below!

Bateman, who we adore for his funny side, is co-starring with Reynolds in the summer comedy The Change-Up, out August 5.

Also at the party was newly single Olivia Wilde.
