Penelope Cruz and Salma Hayek are sisters, not lovers!

Vanilla Sky star Penelope Cruz has quashed rumours of her being in a gay relationship with best pal Salma Hayek, insisting they bond as sisters, and not lesbian lovers.

The two have been close friends for 6 years and photos had surfaced recently that suggested that they were perhaps more than just friends. One example is the provocative picture of them on the red carpet where Cruz is grabbing Hayek's backside.

However, on Late Show With David Letterman on Tuesday night (January 9, 2007), when the host showed the audience several photos Cruz had taken of her good friend Hayek, the Spanish beauty patiently defended each photo, especially the one that fuelled rumours that the two were romantically involved.

"You know what they've been saying because of that picture? We are like sisters and we have some sense of humour... ," Conatctmusic quoted her, as explaning.

"We did that in front of 100 photographers and the story now is that apparently we are lovers. I'm sorry to say, that is not the case!" she added.
