Showing off her brand new hair extensions, Hilary Duff was spotted out with boyfriend Mike Comrie in Toluca Lake on Friday (July 10).

Toting a magazine in-hand, the former " Lizzie McGuire" star and her hockey star beau were dressed casually in workout gear as they carried about with the day’s business.

As previously reported, Miss Duff spent the previous evening getting prettied up at Ken Paves Salon – where she debuted her sexy long coif.

She’s currently gearing up to film her guest role as Olivia Burke, a movie star who enrolls at NYU in search of a traditional college experience, on the hit CW show "Gossip Girl".
