London: Pop singer Ricky Martin is hoping to add a daughter to his family this year. The openly gay singer-actor, who is set to star in a Broadway revival of the musical 'Evita' in March, already has three-year-old twins Matteo and Valentino via surrogate but now wants to have a sister for his little sons, a magazine reported.

"I think that I'll do it later on this year, so that (the kids) are not too far apart in ages. A little girl! But we're going to talk about that later on. It would be irresponsible to do it now," he said.

While Martin, 40, is hoping to add to his family, he said he and boyfriend have no plans of marriage in the near future.

"We are not talking about it, we're not thinking about it. But I'm so happy that in Europe we have the option. It's amazing to think that we can say, 'I feel like it. I'm ready. Let's go,'" he added.
