According to TMZ, they split on Monday, and she wants full custody of their 1-year-old son Sebastian. She's willing to give him visitation. They have only been married for a year.
She sites "irreconcilable differences" as the reason or the breakup, but there's talk that cheating might be the real reason why. Nick Cannon just signed on to rep Amber, and when a photog asked her about their relationship, things seemed a little awkward. Could he be the reason they split? There wasn't anything listed in the papers about that...
As for the cha-ching? Well, they took Kanye West's advice and got a prenup. Still, sources say the breakup is pretty bitter.
We wish the two of them the best during this difficult time.
