Tennis hottie Anna Kournikova and her warbling beau Enrique Iglesias hit up the Sony Ericsson Open at Crandon Park Tennis Center in Key Biscayne, Florida, on Thursday to watch Serena Williams defeat her sister Venus.

But while it was Serena racking up the victory, all the celebration seemed to be occurring in the stands, as Iglesias and Kournikova engaged in a PDA session.

Anna might as well get in her loving now; she'll probably be too tired after participating in the Nautica South Beach Triathlon, benefiting St. Jude Children's Research Hospital, on Sunday.

Not that she hasn't been preparing for it. "I work out all the time," Kournikova tells the Miami Herald. "If I don't sweat every day, I feel weird."

Funny, we're feeling a little bit sweaty—and weird—ourselves right now.
