Aaron Rodgers photobombs Olivia Munn's video

We know Green Bay Packers quarterback Aaron Rodgers is fond of the photobomb, but this is more than just slipping into the background of still frame.

Check out Rodgers, in the video above, by his actress girlfriend Olivia Munn, who appears to be practicing some kind of swordfighting, perhaps for an upcoming role.

Rodgers said in an interview this month that he's been spending time with Munn in Montreal, where she’s shooting the latest X-Men movie.

Or maybe it's some new training method that the two-time NFL MVP is working on to prepare for the upcoming season.
