Selena Gomez had a wardrobe malfunction over the weekend, showing a little more skin than she intended while on stage.

The “Slow Down” singer performed live in Boston on Sunday at the 103.3 AMP Radio Birthday Bash, a free concert held at City Hall Plaza. When the thigh-high split of her skirt opened at the front while Gomez was dancing on stage in a backless chiffon ensemble, she accidentally flashed her nude underwear.

Despite the minor wardrobe malfunction, the 20-year-old model, who has been linked to Austin Mahone and Ed Sheeran, continued to perform admirably.

According to Boston.com, Gomez was part of a lineup that included Jason Derulo and “Boston’s Boy” Sammy Adams.

Selena has accidentally flashed her Spanx on stage before due to a wardrobe malfunction. She teased the 2011 Jingle Ball with sexy flashes.

“Stars Dance,” Gomez’s debut solo album, will be released worldwide on July 23. She’ll be on the road in August in Canada and early September in Europe before returning to the United States in October.

According to MTV, the new album will be inspired by Gwen Stefani’s “Hollaback Girl.” Since her breakup with Justin Bieber, Selena has been focusing on her new music. “She wants a sexy man,” a source told HollywoodLife.com. According to the source, she is attempting to avoid being distracted by boys, and the best way to do so is to stay “focused on herself, growing as a performer, and making her fans happy.”

After the show, Gomez took to Twitter to express her delight and gratitude for the “amazing crowd.”

‘What an amazing crowd! Thank you @1033ampradio #AmpBdayBash Getting stoked for my tour!’
