A good look?
Jessie, 25, is never one to shy away from making a fashion statement so we really shouldn't be surprised that she pushed the boat out for tonight's star-studded ceremony at the O2 Arena in London.
Her sparkly number was courtesy of Julien Macdonald's SS14 range.
Jessie has been switching between her trademark short cropped hair and long extensions all week, so we weren't sure what style she would choose for tonight. Well, we can now see she went for jet black, mermaid like waves.
The star is nominated at this year's Brit Awards in the 'British Female Solo Artist' category but she'll face competition from Birdy, Ellie Goulding, Laura Marling and Laura Mvula.
However, she does have a Brit Award stashed away in her cabinet at home already after picking up the Critics' Choice prize in 2011.
