Miley Cyrus has got new hairstyle. The "Wrecking Ball" singer showed off the new hairdo which is completed with bangs as she attended 2013 KROQ Almost Acoustic Christmas on Saturday, December 7 in Los Angeles. The 21-year-old star wore all-black outfit at the event. She also had bright red lipstick.

The next day, Billy Ray Cyrus' daughter took to Instagram to share a fun photo of her with a friend. "Red wine & plastic cups #classylassy," she captioned the snap. The star, however, did not say anything about her new hairdo.

On Friday, the singer performed at KIIS FM's Jingle Ball and twerked on a bad Santa who held a bottle of alcoholic drink concealed with brown paper bag. "You are a VERY BAD Santa @CheyneThomas," Miley wrote on Twitter, sharing a photo of the stage act. "Bad Santa #KISSJingleBall," she captioned another photo with the actor.

"[She] was full of energy giving lots of spark throughout her performance. She was the perfect guest to close the evening, It seemed that most concertgoers were there to see Miley. The arena was completely packed until she left the stage," a source told Us Weekly about the performance which took place at Los Angeles' Staples Center.
