Ronald Shane Modica is speaking out about his ex-wife Michelle “Bombshell” McGee and her alleged affair with Sandra Bullock’s husband Jesse James, usmagazine.com reports.

Modica — who unsuccessfully filed emergency court papers last Friday for full custody of Avery, his five-year-old son with McGee — says that his own marriage suffered as a result of his wife’s preoccupation with the Monster Garage star.

“We had problems during our marriage because of her obsession with Jesse James,” Modica tells The Insider. “I once walked into the salon that she owned and she had our wedding photo up there on her mirror and there was a cut out picture of Jesse James’ face over my face.”

The ex-husband also explains that James' affair with McGee began in May 2009 -- and that McGee made inflammatory accusations about James and Bullock’s union.

Bullock and James have been getting in touch with lawyers just in case things get messy after news of James’ alleged infidelity came to light, according to TMZ. Sources say Bullock’s reps have been in touch with several top divorce attorneys, including one who represented Charlie Sheen, Heather Locklear and Michael Jackson.
