Paris Hilton seen kissing Cristiano Ronaldo.

Paris Hilton has been seen kissing soccer star Cristiano Ronaldo.

The socialite reportedly spent hours "swapping spit" the handsome sportsman after they met at Los Angeles club MyHouse on Wednesday night (10.06.09) - less than 24 hours after she split from boyfriend Doug Reinhardt.

A source told X17Online: "Cristiano and Paris were all over each other swapping spit the entire night! His table needed every waitress in the building to service the large quantities of alcohol, and he spent in excess of $20,000 on champagne and drinks."

The 28-year-old heiress and her sister Nicky started their evening at trendy eatery Nobu, where onlookers say Paris was "visibly pining" for 'The Hills' star Doug, who she dated for six months before they split.

A restaurant source said: "The Hilton sisters showed up at about 10.20pm and sat on the outside patio. Paris wasn't her usual chipper, chatty self - she looked absolutely miserable.

"She was clearly flying under the radar with her sister. She had a couple of cocktails and she was fiddling with her phone throughout the entire meal."

The sisters left the restaurant at around 11.20pm and headed to the club. Once inside, Paris instantly made a beeline for Cristiano's table.

The randy pair left together at 3am, driving straight to Nicky's house in West Hollywood.

Cristiano - who is moving from English team Manchester United to Spanish club Real Madrid in a reported £80 million transfer - was videoed leaving the mansion at 5am with a cheeky smile on his face.
