Katy Perry and Russell Brand a “Hot and cold couple”

New York(ANI): Katy Perry and Russell Brand spend an awful lot of time bickering like a husband and wife on the verge of divorce, and pals call them a “Hot and cold couple". The couple is reportedly set to marry this fall.

"They fight and make-up constantly," the New York Daily News quoted a Perry"s friend as saying. Last September, at a Friend"s wedding reception, Brand, a former sex and heroin addict as well as a recovering alcoholic who"s been sober for seven years, frowned upon Perry"s hard-partying ways.

"[Russell] got angry with Katy because he thought she had drank too much" that night, says the insider. Perry "ended up staying with a friend who has a place in N.Y.C." Brand "went back to the couple"s hotel room alone," said the source. Meanwhile, Perry has issues with Brand as well, particularly when it comes to her beau"s reputation as a comic Casanova.

"There have always been fights about other women - despite Russell talking about how much he loves Katy all the time," said the insider. One of those quarrels took place shortly before last month"s 2010 MTV Movie Awards, where Perry performed and Brand was a presenter.

"Katy suspected [Russell] of cheating and it wasn"t the first time," revealed the insider. But shortly after the show, Brand and Perry were hand-in-hand at the awards-show after-party at L.A."s Las Palmas nightclub. "It"s a cycle," Katy"s friend says of the "Hot and Cold" couple. Representatives for Brand and Perry did not respond to requests for comment.
