Scarlett Johansson & Sean Penn Work Up a Sweat (PHOTOS)

ScarJo & Sean Serious?
Expert weighs in on Hwood's new couple!
A couple that works out together, stays together!

Check out Scarlett Johansson and rumored boyfriend Sean Penn going for a jog in Los Angeles on Sunday, but it wasn’t a lovers only activity. Owen Wilson was also along for the run as the trio worked up a sweat not far from Sean’s Malibu home.

Are Penn and Scarlett getting more serious?

Ryan Reynolds’ ex certainly has been spending a lot of time in Malibu with Sean. While the duo may seem odd at first, S & S make a pretty perfect couple. Sean and ScarJo have been seeing each other since January.

Johansson, 26, has been in Los Angeles filming We Bought a Zoo with Matt Damon. Penn, 50, can be seen next alongside Brad Pitt in their mysterious flick The Tree of Life.
