Happy Birthday, Ryan Kwanten! Behold His True Blood Shirtlessness (PHOTOS)

Jason Stacked-House spends more time shirtless than clothed, so believe us — rounding up his ab-flashes from True Blood in honor of his 36th birthday today required plenty of hydration.

Of course, it doesn’t help that even when Jason’s wearing a shirt, it’s almost always unbuttoned. Sigh, what can we say? The six-pack needs to breathe. 

Grab some water, and then click through for the birthday boy's hotness!
