Her tummy has been the most closely watched in the world for years as this stage, and few have had to fight off as many is she/isn't she pregnancy rumors as Jennifer Aniston.  The 47-year-old, who is married to fellow actor Justin Theroux, has previously spoke of her desire to start a family, and now In Touch magazine are claiming they have the confirmation from an exclusive source that Jennifer is indeed expecting her first baby. "She’s pregnant," a friend of the couple supposedly told the US magazine. "She and Justin are ecstatic. Jen has wanted to have a baby with Justin for years. Their baby news came at a bad time in her life, too — she just lost her mother, and she and Justin almost broke up. But now this surprise pregnancy has turned the worst of times into the best of times." Jen and Justin, who tied the knot last year after a four year romance, were recently snapped frolicking on the beach while on holidays in Bahamas, and the normally very slender actress does indeed appear to have a slightly more rounded tummy than usual.   Now, the world at large are still waiting on confirmation from Jen's reps on this one, but we are going to let you guess for yourselves: Baby or just a little holiday bloat?!
