As biker Jesse James tries to build bridges with wife Sandra Bullock, fresh allegations have surfaced involving another alleged affair.

A second woman has now claimed to have had a relationship with the star during his marriage to The Blind Side actress, Sandra Bullock.

People reports that 35-year-old Melissa Smith has told a US tabloid she had a two-year romance with Jesse after they met using social networking site, MySpace, in 2006.

Like Michelle McGee - the first woman to come forward - Melissa is a heavily tattooed stripper.

Colleagues of Jesse - who owns a bike shop - claim that his infidelity was an "open secret" amongst the staff.

Sandra is yet to speak about her troubled five-year marriage, and is believed to have moved out of her marital home.
