With L'Oréal Paris being an official partner of the 2011 Cannes Film Festival, we've already seen L'Oréal girls Cheryl Cole, Diane Kruger and Aishwarya Rai hitting the Croisette - so we knew it was only a matter of time before new kid on the block Gwen Stefani made an appearance.

The 41-year-old teamed her belted all-in-one with tight white blonde curls, heavily lined eyes and a neon pink lip.
What do you think of Gwen's daring jumpsuit: hot or not? Let us know below!
