Jennifer Lopez dives into work wearing a dolphin tattoo as Marc Anthony 'begs her to take him back'

Jennifer Lopez is not letting her divorce drama get in the way of her new job.

The 42-year-old star, ever the consummate professional, was all smiles on the set of her new film What To Expect When You're Expecting in Atlanta, Georgia, yesterday.

Dolphins equal no drama: Jennifer Lopez is all smiles on the Atlanta Georgia set of her new film, What To Expect When You're Expecting yesterday, safe in the knowledge that ex-husband Marc Anthony is begging her to take him back

Her outing comes amid rumours her estranged husband Marc Anthony is begging her to reconsider their split.

'His mood shifts from blaming her to begging her to take him back to telling her she is destroying his life,' a source told Us Weekly. 

When it comes to cutting a divorce deal: 'He's being difficult on every little point. He wants to prolong things so she reconsiders.'

But J.Lo is said to be loving her new-found singledom and has no intention of reuniting with Marc. 

'She is very happy,' a second source proclaimed. 'She is surrounded by love.' 

She certainly seemed content while filming scenes for her latest film at the Georgia Aquarium on 4 August. 

Wearing a grey dress and big black boots with her hair styled in a loose bun, the actress seemed happy and relaxed on set as she text on her phone. 

She showed off a dolphin tattoo on her right shoulder, which may be for the film, or may be in honour of the football team she and her soon-to-be-ex own, the Miami Dolphins.

The film is a loosely-based adaptation on Heidi Murkoff and Sharon Mazel's top-selling pregnancy guide, What To Expect When You're Expecting. 

Jennifer plays Holly, a woman who adopts a baby abroad after having problems conceiving. 

The movie, which is meant to be released on Mother's Day of 2012, also stars Cameron Diaz, Elizabeth Banks, Brooklyn Decker, Chace Crawford and Matthew Morrison. 

In reality, the sultry Latina had no problems conceiving: she is the mum of three-year-old twins Max and Emme. 

If only life were like the movies, then J. Lo would have had her happy Hollywood ending. 

Although her latest marriage didn't work out, she's confident that she will find the one. 

'Sometimes it doesn’t work - and that’s sad. But I remain an eternal optimist about love,' she told Vanity Fair. 

She added 'If I stay, then I am not doing the right thing for me. I love myself enough to walk away from that now.'
