Is Peta Murgatroyd, the Dancing With the Stars pro paired with Sean Lowe this season, coming between The Bachelor star and fiancee Catherine Giudici?
According to tabloid reports, the two are "fighting constantly," and Peta's relationship with Sean is the root cause. According to celeb news mag L&S:
"The couple were caught having a major public fight at an LA hot spot, and again two nights later on the way back to their separate units in their apartment complex."
In a second fight, two days later, Catherine called Sean "annoying," and was fed up with him spending more time with Peta in rehearsal than with her.
