Because she's worth it! Teenager wins starring role alongside Cheryl Cole in L'Oreal advert

With a flick of her hair and uttering that ‘Because I’m worth it’ line, she looked like a natural model.

And Irish teenager Kellie Anne Purtill clearly caught the eye of judges too – winning the chance to star alongside Cheryl Cole in a L’Oral Casting Crme Gloss TV campaign.

It is an exciting opportunity for the 17-year-old, who bagged the gig after she entered a Facebook competition to appear in the campaign. Kellie Anne posted a video where she showed off her best hair-toss and delivered the brand’s catchphrase: ‘Because I’m Worth It.’

Kellie Anne was one of three winners – and her luscious red locks were a hit with the judges.

The teenager has since filmed her moment in the spotlight alongside Miss Cole, the former X Factor judge.

Kellie Anne is a big fan, and admitted her delight on Twitter.

She said: ‘So weird to see my picture beside @cherylcole’s on the L’Oral facebook page.

‘She was soo lovely! Like a big sis! She’s exactly how u think she would be x.

The campaign was filmed in London and is due to be unveiled this week.

Two other winners, Robyn Harker and Sarah Baldwin, also got the chance to meet Cheryl.

And to make the trip even more memorable, the trio enjoyed a night out at Shrek The Musical, to watch Miss Cole’s fellow Girls Aloud star, Kimberley Walsh perform.

Kellie Anne follows in the footsteps of some of the world’s most glamorous stars by uttering the famous catchphrase for L’Oral.

American Idol judge Jennifer Lopez, Desperate Housewives star Eva Longoria and Beyonc have all appeared in campaigns for the brand in recent years.

While Diane Kruger, Gerard Butler and Rachel Weisz are also among L’Oral’s celebrity ambassadors.
