From her supporting role in Mean Girls to staring alongside Channing Tatum in Dear John, which hit theaters on Friday, Amanda Seyfried has evolved from the girl next door to a Hollywood sexy kitten! The gorgeous blonde actress made a name for herself with her smash hit Mamma Mia!, and also scored herself a hunky beau (co-star Dominic Cooper).

While her former Girls Next Door costar Kendra Wilkinson was busy Friday preparing for her weekend nuptials, Holly Madison exuded every bit the single lady she is.

Looking gorgeous in a metallic one-shouldered mini,  Holly flaunted her assets and her accomplishments-she's just completed her first week in the sexy revue "Peepshow," at  Planet Hollywood.

Madison celebrated at PH's resident hotspot Prive with pals, but we hope she got some shut eye. The blonde will likely be jetting back to Los Angeles for Kendra's Saturday I Do's.
