Calvin Harris, girlfriend Aarika Wolf split?

DJ Calvin Harris and model Aarika Wolf have reportedly called it quits, soon after making their red carpet debut together at the Grammy's after-party.

They had been dating from last seven months, reported E!Online.

"Calvin and Aarika split around the time of the Brits (awards) last month. They were both into each other for a long time but it just didn't work out and they'll stay friends," a source said.

"Calvin is always really busy and is constantly travelling around to DJ gigs so he's happy to be single for a while," the source added.

Harris' representative refused to comment on the issue.
