Adam Levine held his bachelor party in Las Vegas this week.

The Maroon 5 frontman - who is set to wed Behati Prinsloo later this year - headed to the gambling capital following 'The Voice' USA finale, where he was joined by a group of around 50 male friends.

They ate at the N9NE Steakhouse on Wednesday night (21.05.14) and were in high spirits socialising with other diners.

A source told People magazine: ''Everyone in the restaurant recognised him. He was saying hello and chatting with everybody in the restaurant.''

The group stayed at the Palms Casino Resort's Hardwood Suite in a 10,000 sq ft room which came complete with a private dancefloor, 24-hour butler service and indoor basketball court.

The 'Voice' USA coach recently ditched his brown locks for an eye-catching peroxide blonde style last week and, although he likes his new style, he insists will dye it back before his nuptials.

He explained: ''I'm probably gonna have to get rid of this before the wedding happens. I love my hair but it's not gonna be this way forever - trust me. I'm gonna have to change it back for something or other. I'm enjoying it.''
