Lance & Reichen Break Up

Former 'N Sync star Lance Bass and Amazing Race winner Reichen Lehmkuhl have decided to end their relationship.

According to Lance Bass' publicist, Cindy Owen, the couple has broken up. News of the announcement supposedly came as a surprise to Reichen, who was unaware that Bass issued a statement

The split, however, was a mutual decision by the high-profile couple, and came after a period of heavy fighting between the guys.

"They had been fighting a lot lately," says one source. "They tried a lot of things to make it work - even opening up the relationship - but they would just fight all the time towards the end. It wasn't working."
