Power Couple Split After Racy Bachelor Party; Ex-Fiance Sues for $60,000

March 16, 2011— -- Weeks before her planned wedding, Lauren Serafin says she learned her fiancé Robert Leighton likely had an illicit encounter at a bachelor party in Las Vegas.

Now the former couple may be headed to court after Serafin slapped her alleged philandering fiance with a complaint in the Circuit Court of Cook County, Ill., for breach of promise to marry and other relief.

The bride and groom were close to tying the knot when Serafin alleges in the suit that she discovered text messages sent to her fiancé indicating "something happened" during his trip to Sin City.

After weeks of denial and numerous attempts to discretely move out of the couple's shared apartment, Robert Leighton confessed to "hooking up" with a woman named in the lawsuit as Danielle, according to court papers.

In the suit, posted on the legal news Web site On Point News, Serafin says the couple had a two-year relationship before Leighton proposed in July 2009. The following year, weeks before the "I dos," Leighton traveled to Las Vegas with family and friends for a bachelor party.

And, this is where things get murky. The complaint alleges Leighton and Danielle met "less than 24 hours prior to engaging in sexual intercourse."

The former fiancee claims that though she found text messages between Leighton and Danielle, her fiancé denied anything happened, apparently believing the mantra "what happens in Vegas, stays in Vegas."

In the following weeks, Leighton would allegedly admit he "made out" with the other woman, Danielle, before eventually disclosing the two "hooked up." Leighton would go on to blame Serafin for his indiscretion before informing the want to-be bride that he would not marry her, the court papers allege.

Since ending their engagement Serafin says she has suffered humiliation and depression and is seeking $62,814 as reimbursement for wedding preparations.

In a complaint to the court, filed by her attorney Enrico J. Mirabelli of Nadler, Pritikin, & Mirabelli, the jilted bride alleges breach of promise to marry and intentional infliction of emotional distress.
