Katy Perry, Bruno Mars, Ellie Goulding, Pharrell & Lorde Perform at 2014 BRIT Awards

Beyoncé wasn't the only artist performing at the 2014 BRIT Awards, although she was the most-anticipated one. Also taking the main stage at The O2 Arena in London on Wednesday night (Feb. 19) were; Katy Perry, Bruno Mars, Ellie Goulding, Lorde or Pharrell and Nile Rodgers. Watch their performances in video below! Katy Perry performed, as expected, her new single "Dark Horse". Unlike the Grammys performance, rapper Juicy J couldn't assist Katy for this live showing. Katy gave last night's performance an Egyptian theme. Just like the official "Dark Horse" video will be. Bruno Mars and his Hooligans band rocked the O2 with "Treasure".

Ellie Goulding, looking hotter than ever, performed an acoustic rendition of her hit collaboration with Calvin Harris, "I Need Your Love", before moving to "Burn". Lorde performed her breakthrough single "Royals", and Pharrell, wearing the most ridiculous hat ever, performed "Get Lucky" and "Happy". Pharrell recently caught everyone by surprise with the announcement of his new solo album "GIRL". Out March 3!
