Things are cooling off between Chelsea Handler and her boyfriend of nearly four years. Handler is living on her own again after moving out of the home she shared with Ted Harbert. Whether or not they are still romantically involved, the late-night comic will still have professional dealings with Harbert: he is President and CEO of Comcast, which owns E!, the network behind the comedienne's show Chelsea Lately.

A rep for E! tells "The couple is no longer residing together. Ted has nothing but the highest regard for Chelsea both personally and professionally." The statement follows an initial Monday report from Gawker that Handler and Harbert had broken up, which the E! rep would not explicitly confirm. The website says that "Handler was the one to do the breaking-up." The pair had denied breakup rumors that surfaced during summer 2009.

Handler, 34, began dating Harbert, 55, in 2006, in between the end of her sketch comedy series The Chelsea Handler Show and the beginning of late-night chat show Chelsea Lately. She acknowledged the executive as her "live-in lover" on the series last year.
