It seems like Enrique Iglesias and Anna Kournikova have been together forever, yet they are probably one of the only celebrity couples who hasn't announced they're engaged(again) and/or expecting ... just yet.

Recently the sexy Spanish singer and his bangin' hot former tennis pro girlfriend announced the big news to an exclusive group of close friends at their Miami mansion, according to reports.

Neither one of their reps have confirmed or denied the story, which to us, definitely implies it's a strong possibility. They only way to know for sure? Ms. Kournikova sporting a baby bump instead of her perfectly toned abs.

Congratulations to the happy couple!
