Girls Aloud starlet Cheryl Cole has said that she will buy X Factor judge Simon Cowell teeth whitener for his birthday.

She joked with Hello! magazine that she will "have to think about" what to buy Cowell, who is famous for his pearly whites.

The pair work alongside each other on the ITV show and Cowell is due to turn 50 next month.

During her interview with the magazine, Cole also admitted to being a huge fan of Beyonce, another celebrity known for her perfect teeth.

Since becoming an X Factor judge, Cole has gone on to become an international style icon, having recently appeared on the cover of Vogue.

And she’s not going anywhere anytime soon. Far from it in fact – with Cole’s debut solo album, 3 Words, due to be released on October 26th.

She married Chelsea and England footballer Ashley Cole in July 2006 and is currently working on the sixth series of X Factor.
