Spanish beauty Penelope Cruz and her actor boyfriend Javier Bardem are reportedly planning to marry in December.

"They will marry very soon, maybe even over the holidays. Since she and Javier are from Spain, she'd love to have a Spanish designer create her dream gown," a source close to them was quoted as saying by contactmusic.com.

It is believed the dress could be created by the House of Balenciaga, which was founded by Spanish design house Cristobal Balenciaga. Balenciaga had also designed actress Salma Hayek’s wedding gown.

"Salma's dress was specifically designed for her by the company's creative director, Nicolas Ghesquiere, and it was just beautiful. I'm sure they would be more than thrilled to create a gown for Penelope, it will be the most important dress of her life," the source added.
