As if one sexy Cruz woman wasn't enough ... there's two!
Penelope Cruz stepped out with her sister and fellow actress Monica at a dinner for L'Agent by Agent Provocateur and Net-A-Porter at Sibyl Colefax & John Fowler Antiques in London last night (Oct. 9) -- and the siblings undoubtedly turned heads. The sisters, who both gave birth to babies in the last few months, wowed in black ensembles, giving their best sultry stares.
Monica, 36, welcomed daughter Antonella in May and Penelope, 39, gave birth to her second child with Javier Bardem, baby girl Luna, in July.
As for Monica's feelings about her older sister, the Spanish star admits there's no rivalry between them.
"I have been raised to value my family. Penelope and I never fight, we have a really, really good relationship," she told the Daily Mail in 2007. "It makes me angry and sad when people ask if we argue because I can't imagine a family being any other way."
