Jennifer Lopez Happy and Filming ‘What to Expect When You’re Expecting’

In case you missed the memo, Jennifer Lopez is not dwelling over the split with husband Marc Anthony.

The mother of the three-year-old twins Max and Emme is hard at work filming What to Expect When You’re Expecting in Atlanta, which co-stars the long-legged Cameron Diaz, Chris Rock, Chace Crawford and Joe Manganiellowhich the DailyMail forgot to mention. Really? Have you seen this man shirtless?

Emme is exhibiting similar fashion taste to mommy JLo – although Lopez opted for a less glamorous baggy trousers, sweater and oversized tote bag – accessorizing a gold bracelet and yellow nails with a dove grey dress. While little Max enjoyed being mom’s number one man.
