Enrique Iglesias and Anna Kournikova share first baby photos of their newborn twins

Enrique Iglesias has shared the first picture of one of his twins.

The Hero hitmaker and his longtime partner Anna Kournikova were said to have welcomed their twins - thought to be called Nicholas and Lucy - into the world in late December and Enrique has now confirmed the arrival by sharing a snap of one of his bundles of joy on his Instagram account.

Captioning the picture, Enrique simply wrote: "My Sunshine (sic)"

Enrique has kept his personal life - including his relationship with Anna - out of the spotlight for many years and he previously admitted he doesn't think "perfect relationships" exist as there can be "bad times" between every couple. 

He shared: "You go through your good times, you go through your bad times. It's a tough thing for me to believe there's such a thing as the perfect relationship. I don't think that exists."

And Enrique couldn't help but gush about Anna, who he says is the "coolest girl in the world".

He said: "Firstly, she's the coolest girl in the world. And she understands who I am, to the point where she's willing to sacrifice her personal time with me and let me do my music. It's a huge sacrifice and I respect that tremendously."

And the 42-year-old singer previously claimed he and Anna already live the life of a married couple in many ways.

He explained: "We're just as happy. There comes a point when you've been with someone for a certain amount of time that I believe that you are like, married. I guess the only difference is that we haven't walked down the aisle."
