No one knows whether Enrique's actually gay or not, but since he admits to flirting with both men and women, and avoids answering the question directly - he probably is. He's had a girlfriend for 12 years - Anna Kournikova - but says his father's never met her, and there's been no move to take things further, i.e. as in getting married.
I thought it was obvious that Ricky Martin's that way inclined though.
