Lucas Till celebrates his 21st birthday at Chateau.

Chateau Nightclub & Gardens, the exclusive nightlife destination at Paris Las Vegas, welcomed “X-Men: First Class” star Lucas Till celebrating his 21st birthday as well as Paris Las Vegas headliner and singer-songwriter Barry Manilow, on Friday night.

Till arrived at Chateau with a group of six close friends to celebrate his milestone birthday in true Vegas-fashion. Wearing a dark gray blazer, blue plaid shirt and jeans by Express, the handsome blonde actor walked Chateau’s red carpet, posed for photographers and even signed autographs for a few lucky fans before heading upstairs to get the party started. The up-and-coming young star, who plays Havok in the latest installment of the smash hit X-Men movie series, entered the club around midnight and was escorted to his table in Chateau’s luxurious VIP area. The group enjoyed Grey Goose vodka with cranberry juice and Red Bull while DJ Casanova spun the soundtrack to Till’s birthday celebration and “Happy Birthday Lucas” scrolled across Chateau’s state-of-the-art LED screen behind the impressive marble fireplace DJ booth.

Manilow made his way to the opulent nightclub after wrapping up his popular show at Paris Las Vegas with a large group of friends and took over a VIP cabana on Chateau’s terrace, overlooking the Las Vegas Strip. The famed crooner sipped on scotch and soda.
