Katy Perry’s friend accuses Russell Brand of cheating

Katy Perry’s best friend has hinted that Russell Brand cheated on her.

Jewellery designer Markus Molinari retweeted a post by actor Jon Schaech, who is also friends with Katy Perry, which was about adultery, and directed the tweet suggestively at Russell Brand.

“Seeee Russell! RT @JohnSchaech: Cheating is easy, try doing something challenging and be faithful,” he wrote.

Speaking to RadarOnline last year however, Perry was adamant that Brand would never have cheated on her.

“He’s made no secret of what his life was like before me, but that’s then and this is the future,” she said, “He’s cheated in the past but he knows how good he has it with me and I know he’d never do anything to jeopardize that. I trust him 100 percent.”

Earlier this week, Baptiste Giabiconi confirmed that he is dating Katy Perry.

A rep for the Chanel model told the New York Post: “It’s new, they’re feeling it out, but they’re spending a lot of time together.”

Giabiconi, who is the highest paid male model in the world, is thought to be considering moving to LA to be closer to the singer.

The pair first sparked rumours of a romance between them when they were spotted getting cosy together on the front row of the Chanel show during Paris Fashion Week in February 2012.

They were spotted again the same week enjoying dinner together, before hitting the town and partying the night away.

Last week, Giabiconi was snapped waiting for Katy Perry to arrive at the Gare Du Nord train station in Paris.
