Actor Jackson Rathbone (a.k.a., Jasper Hale) is evening up the odds on the set Twilight set. Fellow actor Alex Meraz, who plays werewolf Paul in the series, welcomed his first son last month. Now Rathbone is adding a new member to the vampire clan! The actor and his girlfriend Sheila Hafsadi welcomed their first child, son Monroe Jackson Rathbone VI, on June 5th. “Sheila & I couldn’t be happier to have such a beautiful, healthy baby boy, Monroe Jackson Rathbone VI,” the actor tweeted.
