Olivia Munn has over 2.7 million followers on Instagram -- why not show off a little?
The 40-year-old actress took a nice tropical vacation over the holidays, and took some thong bikinis with her. Now she's letting us all see.
The former 'Attack of the Show' host followed that up with some more bikini pics -- this time from the back.
You can catch Munn in the show "The Rook" that airs on Starz.
