Britney Spears has experimented with quite a few hairstyles over the years, but other than shaving it off, she has rarely gone too far outside her comfort zone. Lately, however, she’s been tempering her newfound sleek and chic look with some playfulness, and fans seem to like it.

Spears rocked some rainbow extensions last week at the iHeartRadio Music Festival in Las Vegas, making it clear that she came to party and wasn’t going to leave until the house was brought down.

“This is Vegas, baby, so we’ve got the world’s most insane deejays here to keep the party going all night long,” she said.

Spears also said she was a fan of the music festival because of the diversity of music fans when she joined Ryan Seacrest onstage. Whether it was the atmosphere of Vegas or just the young, hip influence her new job as judge on “The X-Factor” has had, Spears seems to be enjoying herself lately, and fans are responding.
