Julianne Hough (L)

Julianne Hough flashed her engagement ring for the first time this week.

The 27-year-old professional dancer's massive diamond can be seen in a group photo shared by friend and salon owner Riawna Capri. Hough, Capri and two other women had a girls' night out at Taylor Swift's concert Wednesday in Los Angeles.

Hough and 32-year-old NHL player Brooks Laich announced their engagement last week. The couple have been together since December 2013, and Laich proposed with a six-carat, Lorraine Schwartz-designed ring.

The professional dancer thanked fans for their love and support after the news broke, saying she is "so happy" to be marrying Laich. Hough was previously engaged to Zach Wilson, and went on to date singer Chuck Wicks and American Idol host Ryan Seacrest.

Hough will return to judge Dancing with the Stars when season 21 premieres Sept. 14 at 8 p.m. ET on ABC. Her brother, Derek Hough, Karina Smirnoff and Val Chmerkovskiy are among the pros who are confirmed, with Nick Carter, Bindi Irwin and Victor Espinoza as celebrity contestants.
