James Maslow: 21st Birthday in Las Vegas!

James Maslow snaps a few pics as he celebrates his 21st birthday at Chateau Nightclub & Gardens at the Paris Las Vegas on Friday night (July 15).

The Big Time Rush star turned the big 2-1 at the stroke of midnight and sat in the VIP section with pals during dinner. After eating, the group danced the night away until the early morning hours.

James tweeted, “Last day of being 20! It’s been a great year in large part thanks to my amazingly supportive fans. To many more!!! Xoxo, JM”
