Gwen Stefani goes from her boat basics to red carpet glamour within minutes at Cannes

3:43 PM on 21st May 2011

She might have spent the afternoon lounging on a yacht in her bikini and casual boat attire but by the evening Gwen Stefani was as glam as she could be in a black and white gown.

Gwen strolled onto the red carpet for the premiere of This Must Be The Place in the Armani Prive peep-hole dress with dramatic smokey eyes and red lips.

But just hours earlier she was playing with her sons Kingston and Zuma aboard a luxury yacht in the Mediterranean Sea.

The mother-of-two sunbathed and swam in a little black bikini in-between covering up in a long black skirt and loose white T-shirt.

Stefani was joined by her 45-year-old husband Gavin Rossdale too, but was out of sight on the yacht as she played with their sons.

Kingston, who turns five next week, was lucky enough to get a ride on the back of a Yamaha jet ski with a family friend, but two-and-a-half-year-old Zuma is still a bit too young for the water sport.

After a day on the yacht, the 41-year-old No Doubt star jumped onto a water taxi to be taken to the mainland for the Cannes Film Festival.

The This Must Be The Place premiere was the place to be last night and Gwen was just one of the high profile celebrities to attend.

Sean Penn and Bono’s daughter Eve Hewson star in the film and were joined by Italian director Paolo Sorrentino for the screening.

While A-list guests included Claudia Schiffer, Rosario Dawson and Courtney Love, as well as English socialite Lady Victoria Hervey, and actresses Marisa Berenson and Maison Martin Margiela.

Gwen has been a regular attendee at Cannes this year and spoke on stage this week at the AMFAR Gala – Cinema Against Aids event.

She was modelling a dress for sale in the charity auction and was accompanied by her handsome husband Rossdale, who looked stunning in a classic tux.

Gwen’s glittering column dress with a lace cowl neck detail and copper-coloured belt made her steal the show on the glamorous night.
