Pixie, schmixie, bob, schmob! Julianne Hough bucked Hollywood's hair-shortening trend and actually went longer -- debuting new long, blonde extensions via Instagram on Tuesday, Dec. 3. "#changeisgood #longhairdon'tcare," the Safe Haven actress, 25, wrote in a caption beside two split shots of her shaggy, sexy-messy new 'do, in which she poses sans makeup. "#thankyoumybeautifulgirls #nofilter #nomakeup #darkeyebrows #yesssssss." Click here for more pics of Hough.

Hough went long at the Nine Zero One salon in Hollywood, with Riawna Capri doing the honors. Indeed, Capri and fellow stylist Nikki Lee then escorted the Dancing with the Stars alum to Beyonce's Mrs. Carter World Tour concert at L.A.'s Staples Center for a girls' night out. One catch? The extensions process took so long that Hough et al arrived at the VIP viewing party at the arena's Hyde Lounge mid-way into the show!

Hough -- who split with Ryan Seacrest earlier this year -- was in full makeup once she did arrive for Beyonce's big show. Other celebs at the viewing bash included plenty of couples on date nights: Molly Sims and hubby Scott Stuber, House of Cards' Kate Mara and beau Max Minghella, Kelly Osbourne and fiance Matthew Mosshart, Zoe Saldana and hubby Marco Perego, and new parents Wiz Khalifa and wife Amber Rose.
