Robert Pattinson & Kristen Stewart

The former couple - who split in May - have reportedly been spending time together behind closed doors, and friends say it was the actress' mother Jules who put them back in touch as she and her daughter were
both worried about the British actor's partying.

A source told Grazia magazine: "Jules is like a surrogate mother to Robert in LA and she reached out to him and invited him over to see her with Kristen. They were both very worried about him.

"He's at a low ebb right now and enjoyed seeing Kristen. One thing led to another and they've hooked up quite a few times since in secret.

She has been trying to help Robert get his life back on track. She's still madly in love with him."

However, while the 'Snow White and the Huntsman' actress is hopeful the meetings could signal the start of a romantic reconciliation, her former lover has other ideas.

The source added: "Kristen misses Rob desperately and there is still a lot of chemistry there. It's been a hard few months for them both and she is desperate for them to give their relationship another chance.

"Rob has softened towards Kristen but as far as he's concerned they're not getting back together. This is a temporary state of affairs and he has told friends they don't have a long-term future. He can't face the
scrutiny their relationship always comes under - but with these two, who knows?"
