Gwyneth Paltrow and Chris Martin are "operating like a couple" again.
The 'Iron Man 3' star and the Coldplay rocker - who announced they were separating after 10 years of marriage - have further fuelled speculation they are getting back together after they were seen dining together with their children Apple, 10, and Moses, eight, numerous times in the Hamptons this week.
A source told the New York Post newspaper's Page Six column: "They were operating like a couple, and with the kids looked like a happy family."
On Monday, the family enjoyed a meal at Bay Kitchen Bar in the resort town, and the following day 37-year-old Chris picked up skateboards from sports store Gubbins before joining Gwyneth, 41, and their children at Fierro's Pizza.
It was recently claimed the former couple - who are still living together - had grown closer after the "pressure" to try and save their marriage eased.
A source said: "They haven't made any concrete decision to get back together, but it's a possibility. They're discovering a dynamic that works for them all over again, like when they first got together. They're getting along really well.
"They've loving time together with and without the kids. She didn't want to end the marriage. He's been a great father, and that has helped keep the flame alive. They love each other, and if the romance comes back, they'll go with it if it feels right."
