The pair have been insisting for months that they are just good friends.

But at the awards night, held in New York, Kournikova was seen comfortably perched on the singer's lap kissing him passionately.

"Nothing was going to stop those two," an observer told the Daily Mail.

"They were all over each other."

Denials

The couple met after the tennis player starred in a music video for Iglesias' hit single, Escape.

At London's recent Party in the Park, Kournikova watched from the wings as the Latin Hearthrob performed the hit on stage.

For months they have denied being romantically involved after being spotted in a number of nightclubs and restaurants together.
