Samantha's Summer Couple Pick- Will they sizzle or fizzle?

Jennifer Aniston and Justin Theroux

Ever since her marriage ended with Brad Pitt in 2005, Jennifer Anniston's dating life has been in the spotlight more than any other celebrity's. Her romantic rap sheet includes hotties such as Orlando Bloom, Gerard Butler and bad boy, John Mayer. Jen had everyone buzzing last week when she stepped out with new beau Justin Theroux, an actor, writer and director. They were first seen together in March when Jen was spotted visiting Theroux at the Chateau Marmont in L.A. But more recently, the pair hit the town looking like a couple at the MTV Movie Awards on June 5th. Has Jen finally met someone who will keep her happy? Will she finally be out of the public's eye or with all the attention put strain on the relationship like others in the past? How long do you think this will last? Will Jen's fling finally sizzle or end up in just another fizzle?
