Jennifer Aniston, Kourtney Kardashian and Naomi Watts Lead Today’s Star Sightings

The queen bees of Hollywood are hard at work.

Jennifer Aniston showed off a wavy ‘do — and not to mention, her sexy stems — while walking around on the set of her upcoming movie, Squirrels to the Nuts. Currently shooting in New York City, the comedy flick revolves around a Broadway director who falls for a prostitute and works to make her famous.

Over in Miami, Kourtney Kardashian was busy with mommy duties as she took her youngest child, Penelope Disick, for a fun day at the pool. The mommy-and-daughter duo were both seen sporting coordinating swimsuits. How cute!

Speaking of babies, Australian actress Naomi Watts was spotted sporting a rather large — albeit fake — baby bump on the set of her film, St. Vincent de Van Nuys, in Coney Island, N.Y. Slated for a 2014 release, the movie will also star BridesmaidsMelissa McCarthy and Chris O’Dowd.
