Get The Look: Christina Aguilera's Undone Updo

Christina Aguilera did classic glamour with an edge for her guest appearance on The Tonight Show with Jay Leno.

Teaming her slightly unkempt updo with pillar-box red lips and a black lace figure-hugging dress the diva proved that grunge and glamour needn't be mutually exclusive.

To recreate Christina's mussed-up updo:

1. Run a texturising product through damp hair to create this season's matte finish.
2. Pull the hair back into a high ponytail and secure at the crown with a hair elastic.
3. Leave out a few loose tendrils around the face to create a more dishevelled look.
3. Twist the hair around the base of the ponytail into a bun and secure in place with pins.
4. Gently rub the bun with the palm of your hand to soften the silhouette.
