Fame Flynet 1 / 9

She's on fire! Rebel Wilson is proving to be quite the, well, rebel when it comes to her hair these days.

The "How to Be Single" actress debuted a major hair shakeup in Los Angeles, sporting bright orange tresses!

Rebel was seen with the new 'do after leaving the salon.

The funny lady usually rocks blonde locks, so this new Halloween-like shade is quite a departure for her, although she did briefly color her tips bright pink at the 2015 VMAs.

Rebel donned sunglasses, a black leather jacket, gray jeans and a black and white graphic tee as she sported the fiery hairstyle.

She also showed off her new look on social media in a bit of a "Pitch Perfect" reunion, a gathering that coincided with Rebel's 36th birthday.

"Love these pitches xx," she wrote on Twitter along with an upside-down selfie with fellow "Pitch Perfect 2" costar, Hailee Steinfeld.

Chrissie Fit, who also starred with Rebel in the popular movie, also joined the birthday festivities.

The birthday activities were a fun alternative to what Rebel experienced not too long ago due to some over-the-top One Direction fans. Last month, the actress recalled a moment she had with Harry Styles as they both appeared on "Ellen."

Rebel aggressively hugged Harry and the boy band's fans were less than thrilled.

"Basically I got accused of sexually assaulting Harry Styles," the then-blonde Rebel told Ellen DeGeneres last month as they played a clip from November 2015.

"These little girls, I think they're about 12--very, very unhappy with that. Basically, we're just like two professional entertainers having a good time, and he really enjoyed it. And, I told them that on Twitter, and then they just sent me more death threats."

Rebel joked that she really loves her young men, including Harry, of course, and Justin Bieber, whom she tried to pick up in Las Vegas in mid January at the opening of Jennifer Lopez's show.

"I did pick up Justin Bieber the other night," Rebel told Ellen. "Yep in Las Vegas Justin and I had a moment."

Ellen, as she often does so well, pried for more but Rebel stayed tight-lipped.

"Yeah. We'll leave it at that," she said. "I'll talk to you later and I don't want his fans sending me death threats."
