When: 2005-present

The consensus sexiest woman in Hollywood at the time, Angelina had been divorced twice and had a bit of a cuckoo sex appeal; she and then-husband Billy Bob Thornton wore vials of each others' blood around their necks. Brad and Angelina fell for each other on the set of Mr. & Mrs. Smith, which was a problem as he was still married to Jennifer Aniston. That situation was put out of its misery and a year later Angelina announced she was pregnant with Pitt's child. Brangelina is/are currently engaged.

Smash Probability: Oh yeah. If Brad Pitt and Angelina Jolie aren't having sex, and a lot of it, what hope is there for the rest of us?
