Hollywood actresses and supermodels beware, if you don't look up to the mark, you might just end up getting replaced by the reigning Bollywood queen Aishwarya Rai.

This is exactly the message that was given to Sir Mick Jagger's daughter, supermodel Lizzie Jagger recently.

Brunette Lizzie was signed by Lancome three years ago has dropped nearly one dress size in recent months, triggering concerns about her health.

According to the Daily Mail, 20-year old Lizzie was warned by the cosmetics giants L'Oreal that if she doesn't put on some weight and start looking more healthy, she might be replaced by Rai, as the brand ambassador for their cosmetics line Lancome.

Lizzie, who has been the face of the company's fruit-flavoured lip glosses, 'Juicy Tubes,' is getting far too skinny according to the company bosses, which makes her unfit for the image that the company tries to promote.

"We've asked her to put some weight on. We think she's taking it on board and doing something about it. We very much hope so as she has been a big success for us," the report quoted a source as saying.

Former Miss World, Aishwarya Rai, is being looked at as an option as she was recently signed on as L Oreal brand ambassador.

"If she doesn't listen, though, we will look at bringing someone else in and Aishwarya Rai is one name that has been mentioned as she has recently been signed to the company," the source added.
