He explained: 'There's a two year difference, so I was a little scared. I was like, "How are they going to react?" And I have two dogs so my house is chaotic.'
Adding: 'When we first came home with Masha, I was like, "Oh, how is everybody going to react?"'
Enrique is doing a joint arena tour with Ricky Martin, which was announced on Wednesday morning.
The Spanish crooner said that Ricky, who is a father of four, gave him advice on being on the road with kids.
'We were talking about that, you know, like being on the road with kids. Ricky was giving me some advice. It's tough. It's tough, but it's doable. Obviously, we're fortunate enough that if we want to do it, we can do it.'
Ricky, 48, told the outlet that 'A lot of people say, "With young kids, they need stability." I think we are their stability. If we're near them, they'll feel safe and protected regardless of the roller coaster. They're next to us.'
Enrique added: 'You're not going to separate me from my children.'
Last month, Enrique and Anna both took to Instagram to post several heart-warming snaps of the moment Anna gave birth to their third child.
Confirming the baby's date of birth to be January 30th, the proud parents uploaded their shots with identical captions, which read: 'My Sunshine 01.30.2020.'
