Cyrus debuted a new hairdo at the 24th Annual KROQ Almost Acoustic Christmas in Los Angeles on Dec. 7, a big change from her signature pixie cut.

The 21-year-old singer is now sporting a short bob complete with cropped bangs. See photos here. 

It is left to question if the hairstyle is a wig or an actual haircut? After all, she took to Twitter in November to share a photo of herself in a bob wig.

Still, Cyrus has been open about her desire to grow out her short hair, admitting she misses her longer locks.

"I'm secretly tugging on it every night and taking Viviscal," Cyrus said in August, referring to the hair-growth vitamin supplement. "I'm not going to lie. But I'm going to rock it while I have it." 

The former Disney star is constantly playing around with her looks. She made headlines in 2012 when celebrity stylist Chris McMillan gave her a blond short cut that featured shaved sides and long bangs. It then appeared that she bleached her eyebrows and debuted the new look in a series of photographs she took with some of her celebrity friends, posted on Instagram in November. 

The Wrecking Ball singer also tried out a long purple wig, though that was merely part of her Halloween costume this year as she tried to recreate Lil Kim's controversial look from the 1999 Video Music Awards. 

Cyrus is gearing up for her 38-day Bangerz tour in 2014, which kicks off on Feb. 14 in Vancouver and end April 24 at Nassau Coliseum on Long Island, N.Y.
