Gwyneth Paltrow and former husband Chris Martin reunited once again, this time to celebrate son's birthday on Saturday.

"The pair were snapped arriving separately to a venue in Brentwood, Los Angeles on Saturday for a celebration with the youngster," said Daily Mail. "Actress Gwyneth, 42, opted for a make-up free look as she wore a pyjama-esque matching purple and white spotted top and trouser combo."

A little later, Chris Martin arrived on a Jeep.

According to the publication, which talked to a source, Gwyneth Paltrow and Chris Martin's divorce "is definitely 100 per cent on. They are working out a deal privately and there will be no leaks. This is a very amicable break-up and the resolution is near."

The source added, "Papers will be filed soon and the divorce will be dealt with quickly. They both love their children and they still have the utmost respect for each other. But they are not getting back together."

Despite their divorce, however, the two remained friends. Chris Martin is reportedly dating Jennifer Lawrence, while Gwyneth Paltrow is seeing Brad Falchuk of "Glee."

The Daily Mirror also confirmed the divorce report as it said that Chris Martin and Gwyneth Paltrow "instructed lawyers to divide the custody of their two children Apple and Moses, as well as their £80 million fortune."

Meanwhile, Gwyneth Paltrow failed the challenge to meet nutritional needs under the Supplemental Nutrition Assistance Program (SNAP) or food stamp, amounting to a paltry $29 each week.

She wrote on her GOOP website, "As I suspected, we only made it through about four days, when I personally broke and had some chicken and fresh vegetables (and in full transparency, half a bag of black licorice)."

"My perspective has been forever altered by how difficult it was to eat wholesome, nutritious food on that budget, even for just a few days," Gwyneth Paltrow added.
