Image-conscious individuals looking to achieve a smile makeover using cosmetic dentistry could be encouraged after hearing rumours about Tulisa Contostavlos.

According to the Sun, the stunning 23-year-old has spent £12,000 to improve her pearly whites ahead of the launch of the new series of The X Factor.

The newly appointed judge, who replaced Cheryl Cole on the panel, is said to have received dental veneers after previously expressing she was self-conscious about her smile.

A source told the newspaper: "Since she became famous she has become aware they are not perfectly aligned, so she decided to pay for a bit of help."

The N-Dubz band member is one in a long line of X Factor presenters to have work done to improve the appearance of their smiles under the glare of the studio lights.

She recently showed off her stunning figure in a black bikini while on holiday with friends in Ibiza.
