Gwen Stefani ditched her signature red pout to attend the premiere of "The Tree Of Life" during the Cannes Film Festival.

The 41-year-old singer, designer and L'Oréal Paris spokesmodel looked super-glamorous in hot pink lipstick. Stefani's creamy lip color paired well with her smoky eye makeup and voluminous curls.

While this isn't the first time the "Hollaback Girl" has donned pink lips, we think this brighter hue is the perfect summer shade for the rocker mom.
