Jacqueline arrived at the event with her EastEnders co-stars but posed for pictures alone outside London's O2 Arena.
The actress, 21, stunned in an off-white sequinned dress with floor-length overlay, which she teamed with a cream pair of peep-toe heels.
Jacqueline - who plays Lauren Branning in the BBC1 soap - carried a coordinating sparkly clutch bag and styled her long hair in loose glamorous curls.
Despite EastEnders missing out to Coronation Street on the award for Best Serial Drama, Jacqueline still had a great time and partied into the night with her co-stars.
Taking to Twitter, she shared a photograph of herself and Jamie Borthwick, who plays Jay Brown (formerly Mitchell) in EastEnders.
Alongside the snap, she posted a love heart symbol and commented: "Me and Jamie."
