The 'What About Us' star followed in the footsteps of many a celeb by having her lengthy tresses cut into a chic and sophisticated shoulder-skimming 'do.
Taking to Instagram this weekend (10 January), Vanessa posted a photo with her new barnet, adding the caption: "When you ask @seannolanhair for a trim and he just keeps cutting!!!"
(On a side note, how beautiful does Vanessa look without make-up? We're jealous!)
The songstress then stepped out later that day at the Oliver Spencer autumn/winter '15 fashion show during the London Collections: Men, where she was joined by her boyfriend Gary Salter.
Vanessa gave her bouffant its first official outing, styling the lengths in loose curls for a pretty Marilyn Monroe-inspired vibe.
It looks like she also had some colour applied to her strands, keeping her roots her natural brunette hue while adding a hint of caramel to the tips to give an ombre effect.
To go with her fab new bonce, the singer wore a long-sleeved dress designed by Mary Katrantzou which featured a sheer mesh overlay covered in glittery letters, teamed with a fluffy plum clutch bag and black court heels.
