Monica Cruz Penelope actress Ibiza Spain bikini Monica Cruz Penelope actress Ibiza Spain bikini Penelope Cruz's little sister Monica showed that Pene wasn't the only one with the good looks in the family while frolicking on the beach in Ibiza yesterday.

Wearing a sweet white bikini, Monica could almost even be mistaken for Penelope herself!

The sisters are incredibly close and even design a line for clothing company Mango together -- but unfortch that's not the case with Penelope's sister-in-law, who's also named Monica!

“Penelope has known Monica for years, but she definitely got off on the wrong foot as a new family member," a source recently revealed of Javier Bardem's sister. “It may seem trite, but privacy is very, very important to Penelope. She told Javier she doesn’t want his family sticking their noses into their business. If this happens again, it could hurt the marriage.”
