The ex-husband of actress Sandra Bullock who admitted infidelities caused the collapse of their marriage has signed a deal to pen a memoir, Simon & Schuster's Gallery Books imprint said on Tuesday.

Jesse James, 41, has signed a deal for a tell-all book tentatively titled "American Outlaw," that will be released later this year.

A spokeswoman for Gallery Books would not comment on what the deal was worth.

James was vilified by the media when his five-year marriage to Bullock ended days after the popular actress won a best actress Oscar in March 2010 for "The Blind Side." He later admitted cheating on Bullock and their divorce was finalized last June.

Last month the tattooed, motorcycle-riding James announced he was engaged to tattoo artist and reality star Kat Von D. They have been dating since last summer.

"2010 was actually the best year of my life because I fell in love with my best friend. An amazing woman who stood behind me when the world turned their backs," James, 41, told People magazine in January.
