The pop star and the funny man have been the source of Internet speculation for months that their high-profile romance was on the verge of kaput.

On Friday, less than a week after the two were photographed on different continents on Christmas, Brand filed for divorce in Los Angeles citing irreconcilable differences.

"Sadly, Katy and I are ending our marriage," Brand, 36, said in a statement to People. "I'll always adore her and I know we'll remain friends."

US Weekly reported earlier this week that the two had a major blowout, in part because "Katy doesn't think Russell respects her parents' Christian beliefs or her friends."

Brand pooh-poohed the Internet rumors in a visit to Ellen DeGeneris' talk show, where he dismissed the web as a "wicked little liar."

“I’m really happily married... I’m married to Katy,'' he told Ellen DeGeneres. "Perpetually, until death do us part was the pledge. I’m still alive.”
