Chic v casual: Christina Aguilera wore a striking fuchsia chiffon halterneck dress by Alberta Ferretti, while co-star Cher dressed down in trousers and a leather jacket at the Berlin premiere of BurlesqueChristina Aguilera and Cher have been posing in a variety of revealing, designer dresses as they promote their new movie Burlesque around the world.
But after wearing a lingerie-style dress at the London premiere earlier this week, it looked like Cher couldn't be bothered to make an effort at the Berlin screening tonight.
While Aguilera looked freezing in the snow and -3C in a flowing pink halterneck Alberta Ferretti dress from S/S 2011 Collection, her 64-year-old co-star turned up in a leather jacket, plain black trousers and a white scarf.
Baby's, it's kalt outside': Aguilera looked much happier with a coat on, but took it off to show off her glamorous pink gownAs the snow fell down outside the Cinestar Cinema in the German capital, pop star Aguilera, 29, threw off her warm black coat so she could show off her flowing pink dress for the paparazzi.
But the wind was so strong, at one point she ended up covering Cher's casual outfit with her billowing chiffon layers.
Summery dress aside, Aguilera was also showing off a new hairstyle - Heidi-style plaits across her head.
Heidi hi: Aguilera had pink and blonde braids across her hairCher's ensemble came as a surprise after the risque outfits she has been wearing at Burlesque premieres in London, Los Angeles and Madrid.
But after seeing the weather forecast for snow in Berlin, perhaps Cher decided she'd rather be warm than glamorous.
The pair were joined by co-stars Kristen Bell - who briefly removed her black coat to show off her glitzy blue dress underneath - and Cam Gigandet, who had also wrapped up for the cold weather.
After the film was mauled by critics, the movie's stars have been throwing themselves into the publicity campaign, attending junkets and premieres across Europe, Japan and North America.
