AceShowbiz - A spokesperson for studio boss Clint Culpepper has denied the media mogul split from longtime partner Steve Antin after hiring him to direct "Burlesque". Culpepper is president of Screen Gems, a subsidiary of Sony Pictures, and reportedly asked his boyfriend of 20 years to write and helm the movie musical, starring Christina Aguilera and Cher.

According to New York Post gossip column PageSix, the pair's relationship broke down following a series of bitter rows while shooting the film. A source tells the publication, "Steven moved out of their Hollywood mansion and has been living at the Sunset Tower Hotel since the end of October. He has been telling people it is over with Clint. They've broken up before and always got back together. Some friends expect them to reconcile, but this time Steven is saying things are different. Working together was intense."

However, a Sony publicist denies the rumors, saying, "There is no truth to any of this. They remain together, so whoever is feeding this doesn't know what they are talking about. Clint has one of the most successful track records of any studio head, and 2010 is Screen Gems' best year yet. We could not be more supportive of him."
