Shakira & Rafael Nadal: Dating or Just Friends?

A steamy appearance by tennis champion Rafael Nadal in a new music video by Shakira has sparked rumors that the hotties may be more than just friends.

It looks like that's all we're talking about, though: rumors.

Last week, the pair, who heat up the video for her song "Gypsy," premiering in April, was spotted sharing a cozy meal at the W Hotel in Barcelona, Spain.

"They were giggling. They're very flirty," a source says of the music video shoot.

"They had a lot of chemistry while they were filming, and after as well."

In the "Gypsy" video, the 33-year-old Colombian singer and the 23-year-old Spanish athlete roll around, hold hands, embraces, and look smoldering.

But don't get any ideas.

Shakira is quasi-engaged to Antonio de la Rua, the son of former Argentine president Fernando de la Rúa. While she is reluctant to wed, they have been together nine years and, she says, have been totally monogamous. Nine years!

Nadal, meanwhile, is dating his high school sweetheart, Maria Francisca Perello, and his rep denied a romantic relationship between the "good friends."

Friends may be all they are, but Shakira has still seen Rafael Nadal shirtless up close and in the flesh. For that she is likely the envy of many ladies.
