Surprise! Enrique Iglesias and Anna Kournikova are parents — of two.

The longtime couple are said to have welcomed twins, a boy and a girl, TMZ reports. The outlet says the babies’ names are Nicholas and Lucy, and that they were born on Saturday, Dec. 16, in Miami. Reps for the musician and the athlete did not immediately return PEOPLE’s request for comment.

The newborn babies are the first children for both Iglesias, 42, and Kournikova, 36, who have been together for over a decade and a half.
