Several years later, Cibrian was back to his philandering ways when he infamously got hot and heavy with LeAnn Rimes on the set of the <a href="http://www.nydailynews.com/entertainment/gossip/northern-lights-star-eddie-cibrian-leann-rimes-affair-fabricated-article-1.370257">Lifetime movie "Northern Lights." </a>Glanville and Cibrian <a href="http://www.people.com/people/article/0,,20300442,00.html">called it quits</a> in August 2009, shortly after he and the singer <a href="http://www.people.com/people/archive/article/0,,20306526,00.html">went public</a> with their previously rumored relationship.
