Gwen Stefani: Big Apple Babe

Enjoying a leisurely afternoon, Gwen Stefani was spotted out and about in New York City earlier today (September 7).

The “Hella Good” songstress looked lovely in a white sleeveless top with distressed jeans and strappy heels as she spent time with Roger Federer's wife Mirka.

Gwen and Mirka were no doubt basking in the glory of Roger Federer’s victory over Jurgen Melzer at last night’s 2010 US Open Tournament.

Stefani watched the match at the USTA Billie Jean King National Tennis Center with her husband Gavin Rossdale as well as Ashlee Simpson and Pete Wentz.
