Enrique Iglesiascan’t get over the “incredible” reaction his kids had to his “Escape” music video.

The 46-year-old singer appeared on the latest episode of SiriusXM’sThe Jess Cagle Showwhere he discussed the moment his children — whom he shares withAnna Kournikova— watched his steamy music video of the pair. Thelongtime coupleshare 3½-year-old twinsLucy and Nicholasand 19-month-old daughterMary.

“I think my kids have already seen— well, I think, no, Iknowmy kids have already seen that video,” he said. “And they’re putting two and two together. Like, ‘Oh, really?’ "

Iglesias and Kournikova, 40, first met when she starred in his 2001 music video for “Escape,” which features the duo making out and getting handsy on a bathroom sink and in a car. Sparks flew on set and the singer and former tennis pro began dating shortly after.

“Whenever they hear one of my songs they can actually recognize my voice, which is pretty cool. But when they watch that video, I think it does throw them off a little bit,” Iglesias recalled on the show. " ‘What is Mom doing there?’ you know, ‘with Dad’ you know? ‘When was this?’ It’s actually incredible to watch the expression on their faces. It’s pretty cool.”

Despite the intimate moment on camera in the couple’s throwback video, Iglesias and Kournikova rarely show glimpses into their personal lives.

“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,” he said at the time. “When we first came home with Masha, I was like, ‘Oh, how is everybody going to react?’ "

The following month the “Hero” singershared a sweet videoas he gave each of his children a ride on his back through his yard. “Hang on! 🤪😍,” he captioned the clip.
