SPOILER: Joe Manganiello Shirtless In 'What To Expect When You're Expecting'

There are plenty of reasons to see What to Expect When You're Expecting, in theaters Friday. Loosely based on the canonical pregnancy guide, the romantic comedy stars beauties of both genders, including Jennifer Lopez, Cameron Diaz, Rodrigo Santoro and Chace Crawford.

It also features True Blood hunk Joe Manganiello, who apparently suffers from a shirt allergy. Whether onscreen or off, Manganiello seems adverse to upper body clothing (not that we're complaining).

In What to Expect, Manganiello plays a super-fit bachelor who keeps in shape by doing one-arm pull-ups and jogging circles around stroller-bound dads played by Chris Rock, Amir Talai, Rob Heubel and Thomas Lennon. In a film depicting morning sickness, miscarriage woes and debates about circumcision, Manganiello provides a much-needed dose of eye candy — you know, to help the medicine go down.
