Actress Naya Rivera was a vision in a black pant suit when she arrived at the 2013 MuchMusic Video Awards on Sunday, but she offered paparazzi more than she intended to when she walked onto the red carpet.

The Glee star wore a sheer halter top with embroidered detail in the front, which strategically covered her bust, but she suffered a wardrobe malfunction when her underwear was revealed through her pant's transparent fabric. 

When the 26-year-old arrived on the red carpet with her boyfriend, rapper Big Sean, and paparazzi took photos of the couple and the flashes from their cameras revealed her black underwear.

Rivera and Big Sean, 25, went public about their relationship two months ago when they attended the Los Angeles premiere of the Jackie Robinson biopic movie, 42, on April 9. The actress, who plays the role of the lesbian teen Santana Lopez on Fox's hit musical show, sparked rumors she was dating Sean when she attended his birthday party in May, according to Mail Online.

The 2013 MuchMusic Video Awards was held at the MuchMusic Studios on June 16 in Toronto, Canada.

The event was attended by Taylor Swift, Ed Sheeran, Demi Lovato, Avril Lavigne and several of Canada's hottest celebs in music and television.
