The 20-year-old Disney channel star drank champagne and partied at hotspot Tenjune until 2.30am with ice hockey player Mike Comrie and her entourage.

A source told the New York Daily News: “Hilary looked nothing like the sweet little Lizzie Maguire she once was as she treated Mike to a series of raunchy lap dances.

“She was having a wild night, drinking Veuve Clicquot straight out of the bottle.”

But Hilary reportedly lost her party spirit when the DJ played her new song Wake Up. She is said to have looked embarrassed and immediately stopped dancing.

The actress-and-singer was later helped out of the club by her friends.

Hilary split from Good Charlotte frontman Joel Madden in November last year.

A month later, he began dating Nicole Richie. Joel and Nicole are now engaged and expecting their first child.

Hilary began seeing Mike earlier this year and to prove his love he bought her a new car for her 20th birthday in September.
