11. Karina Bacchi
Italy and Brazil are both countries responsible for disproportionately large numbers of hot women, so when a beautiful blonde Italian-Brazilian actress comes along, you know that Ronaldo is going to give it a shot. Bacchi, who has posed for Playboy, was one of Ronaldo’s rare double flings – they dated briefly in 2007, and then reunited again in 2009. However, dating Ronaldo isn’t her only claim to fame – this bombshell has been on several reality television shows and on several Spanish language television series in her native Brazil, as well as taking on a hosting gig on Brazilian television.
