Celebrity siblings are always making the news. Just look at Britney and Jamie Lynn Spears, or the Jonas Brothers. Well none of the aforementioned family members have ever done what Penelope Cruz and her sister Monica did on tape!

The Cruz sisters appear in a lesbian lip lock on their younger brother's music video, “Cosas Que Contar". And according to a source of FOX Pop Tarts' Hollie McKay, "the lesbian lip-lock between the Spanish siblings was the idea of their brother Eduardo, who was obviously seeking controversial PR."

Fresh off of launching their initial fashion venture, Penelope and Monica Cruz are planning to expand their blossoming clothing empire.

According to recent reports, the Cruz sisters are said to be venturing into the market of sexy duds for plus-size women.
