Watch Meghan Trainor and Backstreet Boys sing ‘I Want It That Way’ together

Meghan Trainor, a self-proclaimed huge fan of the Backstreet Boys, lived a '90s girl dream and got to sing “I Want It That Way” on stage with the boyband themselves. The “All About That Bass” singer joined BSB on Thursday night's episode of Greatest Hits to sing a rendition of the classic song.

Trainor – who also wore a white blazer and talked about her childhood love for the band (especially Brian) – before getting her chance to sing with them, making her the envy of millions of girls. Watch the performance below.
