This is totes why Canada wanted NAFTA! Heather Graham's boobs!
The Hangover III star was spotted walking to set in Vancouver, where her cleavage - btw, the U.S.A.'s chief northern export - turned a lot of heads!
But Heather didn't notice- the pro was hard at work studying her script! Besides, she's used to it!
Heather, who is still looking amazing at a shocking 43 (!!!) is currently working on a new version of Flowers In The Attic.
She looks like she's already prepared- she already has flowers all over the dress! LOLz!
