Bills Star Mario Williams Suing Ex For Engagement Ring

Buffalo Bills star Mario Williams isn't playing when he's asking for his engagement ring from his ex-fiancee, as  it's being reported that Williams is now suing for his ring back.

Williams is suing Erin Marzouki, who meet in Houston while Williams was playing for the Houston Texans, over a hefty 10 karat, $785,000 ring. The two got engaged in February 2011, but this past January, Erin broke up with Williams.

Now the big question is... CAN SHE KEEP THE RING?

In the lawsuit, Williams details how much he spent on Erin while the two were together. Items included an American Express credit card, which she racked up $108,000 in charges in one year -- on top of the $230,000 in other gifts he showered on her that same year, according to court records.

Also, the lawsuit displays the bitterness between the two, as Williams claims, in court documents, that Erin used him for his fame and fortune.

Basically, if you add up the money he shelled out on Erin, he spent around 1,123,000 on her.
