London, Jan 25 (ANI): Cheryl Cole showed off a fuller and glossier pout when she arrived at a London airport yesterday.

And when photographers tried to get a closer snap, Cheryl, 26, raised a hand to cover her mouth.

According to onlookers, her lips certainly looked more pronounced than when she appeared at Wednesdays National TV Awards.

"Cheryl's lips looked completely different. If it was just gloss, her female fans would love to know which one because they seemed plumper and fuller," the Mirror quoted an onlooker as saying.

However, a spokesman for Cheryl said she had definitely not gone for surgical treatments on her lips. (ANI)
