Other Woman in Brinkley Caper Sings

Before she allegedly began an affair with Christie Brinkley's now estranged husband Peter Cook, 19 year-old Diana Bianchi had aspirations of becoming a singer.

TMZ has unearthed some video footage of Bianchi from two years ago performing "Open Arms" at an amateur night competition in the Hamptons.

In the video she says, "I'm a singer/pianist and I don't really have a CD coming out right now but I've been working around usually just places like these trying to promote myself and get people to know me." Well, it seems everyone knows her now, especially after her explosive interview this week with WNYW, the FOX affiliate in New York.

Samantha Cole, yet another singer, has also come forward with similar claims of Cook's infidelity.
