But Kim Kardashian was caught without make-up as she arrived at her local gym gym in her white Ferrari yesterday.
The 31-year-old, who was dressed in tight black leggings and a vest, later hid her eyes behind oversized sunglasses as she dashed into the fitness centre.
She certainly isn't always so shy - just hours later she posted glossy self-portraits of her lighter locks - and buxom figure - on her Twitter page.
She posted pictures from the set of her new campaign for the Kardashian Kollection lingerie line, and she made sure she was the perfect advert for the range as she posed in a coral coloured bra.

She then sent an almost identical but slightly less revealing snap of herself in an untied fluffy white bathrobe, with her hair partially covering her cleavage.
But while her Twitter followers would have been focussed on her ample curves, the businesswoman was more interested in her new hair colour.

Her assets were again clear for all to see, but the star simply asked her fans what they thought about her new hue.
She wrote: ‘I dyed my hair lighter yesterday! I'm loving it! New hair color=new beginnings for me You like?’
But it hasn’t all been fun and photo shoots for Kim after the star recently had to deal with a trespasser on her property, it has been reported.

The website claims it was told by a source that police officers were called to the house and the man in question told them he had a job interview lined up with the reality star.
The man was reportedly given a trespassing warning by the police, who then allegedly drove him back to the airport so that he could book a flight home.
Kim was also using her famous curves to promote her latest venture earlier in the day, after she posed topless with her sisters Khloe and Kourtney in a campaign for their denim line.

Kim posted the racy image to her website and wrote: ‘'Kourt, Khloe and I decided to go natural for our Kardashian Kollection denim shoot with Nick Saglimbeni and pose in only our favorite jeans! What do you think of the pic? I think it’s such a beautiful shot and Khloe and Kourtney both look so stunning! Xo'
They unveiled a campaign for the line last week, which saw each of them sporting a pair of jeans named after them, along with identical fitted white shirts.
However the reality stars then decided to generate further buzz for their denim line by releasing the new image, which shows them protecting their modesty with their arms as they pout seductively for the camera.
