He's cited for his "smoldering good looks and successful crossover appeal." Iglesias, 30, has been linked to Anna Kournikova, who is frequently found on "sexiest" lists herself.
Asked about his most embarrassing sexual experience, Iglesias says, "I've had many, but I'll have to say when alcohol kills the romance — in fact, when alcohol kills everything, if you know what I mean."
Iglesias is followed on the list by singer Pablo Montero, actors Eduardo Yanez and Gabriel Soto, and Wilmer Valderrama of Fox's "That `70s Show."
Valderrama, 25, was listed in People magazine's "Top 50 Bachelors" issue in 2002. He's dated Lindsay Lohan, Mandy Moore and Ashlee Simpson, and has been linked to Jessica Alba and Jennifer Love Hewitt.
"It's very difficult for me to fall in love. Truthfully, I've only fallen in love twice in my life," he says.
The list also includes Enrique Murciano (CBS' "Without a Trace"), Eduardo Xol (ABC's "Extreme Makeover: Home Edition), Robert Grant (Showtime's "Queer as Folk") and Tony Gonzalez, the Pro Bowl tight end for the Kansas City Chiefs.
