Natalie Portman, Home Wrecker like LeAnn Rimes?

Natalie Portman has many reasons to celebrate: she's pregnant and engaged to Benjamin Millepied, the 33-year-old French choreographer of Black Swan in which she stars. (Click here to watch movie trailer.) Additionally, Black Swan has earned at least four Golden Globe nominations and Portman is up for Best Actress.

Yet, is there a dark cloud following Portman when it comes to her personal life? Portman has always maintained a highly-guarded personal life, but her soon-to-be husband, Millepied, has some baggage that can't be ignored.

In fact, it may be apropos for Portman to don the 'scarlet H' (for home wrecker, that is) on her clothes.

According to a report by OK! News, Millepied has broken the heart of Isabella Boylston, his live-in girlfriend from at least 2008 up until filming of Black Swan which began in November, 2009.

Boylston and Millepied were dating when production of Black Swan began according to the report, and Boylston was actually working on costume designs for Millepied's production of 3 Movements for the Pacific Northwest Ballet.

Although Boylston was not interviewed by OK! News, speculation that Millepied "blind-sided" his former girlfriend is mentioned as the two were just very happy one year ago. In fact, Millepied and Boylston were traveling and vacationing last year in different parts of the world and the famed choreographer posted pictures from their vacations on Facebook.

Yet, when Millepied and Portman began working together on Black Swan, Boylston's name disappeared in the media and news of Millepied and Portman's relationship began to surface.

On Monday, December 27, Portman released a statement to Entertainment Weekly, saying, "I have always kept my private life private but I will say that I am indescribably happy and feel very grateful to have this experience."

So what really happened to Boylston? Did Natalie Portman suddenly pull an Angelina Jolie stunt (i.e., stealing Brad from Jen Anniston), by stealing the heart of her fellow actor like LeAnn Rimes did to Eddie Cibrian on the set of Lifetime's Northern Lights made in 2009? At the time of filming, Rimes was married to Dean Sheremet and Cibrian was married to Brandi Glanville.

Now Rimes and Cibrian have divorced their spouses and are engaged to one another, an announcement that just broke this week. Despite being called a "home wrecker" Rimes told ABC's Robin Roberts about the affair, "That's just not me. What happened is not who I am, period. But I do know how much I love him. So I've always said I don't live my life with regret. I can't."
