Victoria's Secret Fashion Show 2016: Lady Gaga, Bruno Mars & The Weeknd Perform

Lady Gaga, Bruno Mars and The Weeknd performed several songs during the 2016 Victoria’s Secret Fashion Show, which aired Monday night. Watch the videos below!

Gaga opened her performance with “Million Reasons” from her new album Joanne. Gaga wore a floral gown for the song, just one of many outfits she changed into during the show. Her most expensive costume of the night was a glittery black jumpsuit with a bejeweled hat that cost a whopping $1 million. The headpiece contained more than 45,000 crystals and took 10 designers more than 300 hours to create.

During the runway show, Gaga belted out her tunes as a bevy of Angels made their way down the down stage. This year’s production was split into six themed sections — Road Ahead, Mountain Romance, Pink Nation, Secret Angel, Dark Angel and Bright Night Angel — with the models showing off different outfits to accompany each theme. It was all taped in Paris just a few days ago.

Prior to the show’s broadcast on Monday, Gaga wrote on Twitter, “Thank u all my angels for helping me remind the world that we all have an angel inside us. Love u girls!! #MillionReasons.” Also performing during the annual fashion event, now in its 21st year, were Bruno Mars and The Weeknd. Take a look below!
