Enrique Iglesias has quipped that he has ''sex for breakfast''.
The 'Hero' singer has been with his long-time partner Anna Kournikova - with whom he has 10-month-old twins Nicholas and Lucy - for 17 years, and he joked that the secret ingredient to keeping their romance alive is plenty of early morning love-making sessions.
He told Vick Hope on UK TV show 'Lorraine': ''Well that's exactly what I do for breakfast!''
Whilst the pair have not rushed to tie the knot, the 43-year-old star hasn't ruled out getting married.
He admitted: ''I mean, when you've been with someone for quite a while, the way I have, it's like being married.
''No, I'm not. I'd like to get married maybe in the future.''
The dark-haired hunk recently confessed he has ''more sex than ever'' since becoming a father.
He spilled: ''It's probably more sex now than ever. The sex has not diminished.''
The couple have been together since 2001, and though they have their ''ups and downs'', the singer couldn't be happier.
He gushed: ''Like any couple, you still go through your ups and downs and it's not always perfect. But it is perfect in a way.
''It's incredible to watch her be such a great mother. It's incredible to watch a mum do what she does, when a mother's instinct kicks in.''
Despite being so happy with the 37-year-old former tennis star, Enrique admitted shortly before their twins were born that he still hadn't introduced Anna to his father, singer Julio Iglesias.
He previously admitted: ''They still haven't met, no. They have to meet at some point.''
Enrique raised eyebrows when he introduced Anna as his wife during a concert in Russia in 2011, but he subsequently admitted he simply got caught up in the moment.
He said: ''It was just meant to be sweet, in the moment. I honestly didn't mean to confuse people. I thought it'd be easier for the audience to understand than if I said, 'my girl'.
''I've never really thought marriage would make a difference. Maybe it's because I come from divorced parents, but I don't think you love someone more because of a piece of paper. And nowadays it's not taboo to have kids and not be married.
''What makes a difference is that you're a good parent.''
