After just 10 months of marriage, Jeremy Renner's wife Sonni Pacheco wants out, and not only is she demanding custody of their daughter Ava, but she's claiming fraud!

In documents filed earlier this month, Pacheco says she and Renner have a prenuptial agreement, but that it's null and void because it was based on fraud. We haven't heard that word thrown around in an A-list divorce since Renee Zellweger and Kenny Chesney split in 2005. And we all saw how that one panned out...

Pacheco cites irreconcilable differences as the reason for their split. Not only is she asking Renner to pay for her moving expenses, but she also demanded that he return her stolen passport and birth certificate. Interesting!

In January of 2013 the news broke that Pacheco was expecting the couple's child, but at the time the two were reportedly not together. She gave birth in March of the same year, they reconciled and THEN they secretly got married in early 2014.

Given their history this doesn't come as much of a surprise, but we have a feeling the worst is yet to come...
