The singer, 18, was pictured outside the O2 Arena in London wearing a very revealing black dress with cutout detail around the bust. It did, however, have a clever nude panel to protect her modesty!
Ella's blonde hair also appears to have been lightened and was curled and swept to one side. Very glam!
After walking the red carpet, Ella took to Twitter and admitted to fans: "Well that was mental. #redcarpet #BRITs2014 @BRITAwards x."
Later on, the was spotted wearing the same outfit to the official Sony Music after party, held at Arts Club in central London, and she partied the night away with Jessie J and Nicole Scherzinger.
Ella was still at school when she auditioned for The X Factor in 2012. The hopeful made it to sixth place in the show but has still landed a record deal with Simon Cowell's label Syco.
Last night, Ella told reporters that Simon is happy with her debut album, which is due to be released soon. She said: "He's really happy with it, which is amazing."
