It’s not odd for celebrities' scorned exes to find love again, but it’s bizarre and a little confusing when they end up dating someone who was the displaced ex of their former lover’s lover!

Shar Jackson, the baby mama and former girlfriend of Kevin Federline, is dating Jason Alexander, Britney Spears’ first husband, and Breaking Celebrity News has the exclusive details about the unlikely new couple.

According to a source close to the situation, Federline’s former fiancee, who he left for Spears in 2004, and Alexander, who was married to Spears for 55-hours, also in 2004, after a quickie Las Vegas ceremony, have been friends for several years, but recently decided to take their relationship to the next step.

“Shar and Jason were introduced several years ago at a gifting suite in Los Angeles and have been friends ever since, but a few weeks ago they began dating,” the source reveals to Breaking Celebrity News exclusively.
