Snapped on Set: Jason Segel & Leslie Mann Work it Out for ‘This is 40′ (PHOTOS)

If this whole “acting” thing doesn’t work out, maybe Jason Segel could get into personal training!

The 31-year-old actor and his co-star Leslie Mann were spotted in LA on Wednesday on the set of their latest flick This is 40, a spin-off of the hit 2007 film Knocked Up.

By the looks of it, Jason was channeling his creepy character while he got a little inapproiate as the two worked on their fitness in the park.

The film will focus on Paul Rudd and Leslie’s married couple from Knocked Up, Debbie and Pete, and is being directed by Mann’s husband Judd Apatow. Megan Fox will also have a role in the film that hits theaters on June 1, 2012.
