But Hough's finger wasn't the only thing sparkling on Wednesday night. The group of gal-pals, which also included Nina Dobrev and Aaron Paul's wife Lauren, donned glittering face paint for the big show.

Last week, the Dancing With the Stars pro announced her engagement to NHL star Brooks Laich in an adorable lakefront photo.

"We are overwhelmed with joy and excitement to share with you our recent engagement!" she gushed on Instagram.

On Thursday, Hough shared crystal clear photos of that gorgeous ring -- detailing the romantic at-home proposal on her blog.

"We stood on the deck, watching the sun set over the lake and listening to our favorite songs," she wrote. "Not even for a second did I expect that beautiful, serene scene was about to become one of the most meaningful moments of our lives. In fact, I was so taken aback when Brooks got down on one knee I completely blacked out! It was like a rush of heat and a wave of uncontrollable emotion swept right through my body."

Hough also opened up about that gorgeous oval diamond.

"The ring itself makes me feel very feminine and takes my breath away every time I look down, which I can’t stop doing, by the way," she gushed. "When it comes to taking it off, forget it. I’ll even wake up in the middle of the night to make sure it’s still there! I never thought I’d be the girl sticking her hand out to her friends and screaming in unison but here I am, shrieking all over Los Angeles."

Hough and her friends picked a great night to take in Swift's 1989 Tour -- watch the video below to see highlights from special guests Selena Gomez, Lisa Kudrow and Justin Timberlake!
