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.''
