Have Russell and Jemima called it quits?

Funnyman Russell Brand and partner Jemima Khan have reportedly taken a break from their relationship just after a year of dating. The couple have also unfollowed each other on Twitter, reported Daily Mirror.

“The relationship has simply run its course,” a source said. The pair had been dating since last summer.

Brand, 39, was a regular overnight visitor at Jemima’s Oxfordshire mansion, which she shares with her two sons from her marriage to Pakistani cricketer-turned-politician Imran Khan. Jemima and Brand were often seen walking arm-in-arm. Earlier this year, a besotted Russell told a chat show: “I’m going to be really kind in this relationship. I haven’t been out there trying to nail everyone. I’m very happy in a relationship that feels very different from anything I’ve experienced before. I feel like it’s grounded in friendship and a sort of love and it’s all very cool and exciting .”

Before Jemima, Brand was married to pop star Katy Perry, 29, and has had flings with supermodel Kate Moss, 40, and Spice Girl Geri Halliwell, 42. Jemima, meanwhile, had earlier dated actor Hugh Grant.
