Zoe Saldana and husband Marco Perego have ‘code word’ for sex but reckon their kids have worked it out

If you're a parent, then chances are you'll have some code words for each other around the kids.

Whether that's to signal some much deserved 'me time' or you have a way of keeping the little ones in line - like Princess Kate has, you'll have invented an entirely different language at this point.

However, what happens when the kids manage to crack the code? Well, Zoe Saldana and her husband, Marco Perego, know all about that.

The Guardians of the Galaxy star and the Italian photographer have been married since 2013, and are parents to twin sons, Cy and Bowie, 9, as well as a younger son, Zen, 7.

The celebrity couple recently appeared on The Drew Barrymore Show, where the topic of 'nude bowling' was brought up.

Talking about a nude bowling club, Drew asked the couple: "The question is, are you comfortable enough to nude bowl?"

"No, never. We can try,” Perego said, to which Zoe laughed: “Who’s to say we haven’t [tried it] already? I mean, when we’re in Europe and in the Caribbean, sometimes we forget our bathing suits and we just go for a swim. But we’ve never bowled.”

Perego then said: “We play Legos naked now.”

“Oh, God, he just found a way to call sexy time ‘playing Legos naked'.” Zoe continued.

However, the jig is now up as the Avatar star then revealed that their eldest sons would ask them: "Are you guys kissing? Are you guys gonna go play naked with your Legos?’ And we’re like, ‘No, we’re not going to do that."

I guess it's back to the drawing board?

Drew found it hilarious, however, replying: “OK, that is the cutest thing ever,” before adding: “Can you imagine what it’s like — maybe I’m asking this to myself — but what it’s like to grow up in that kind of love?

"That’s so wonderful.”

Marco immediately scored points from the Scream star when he asked his wife if she was 'comfortable' as they sat down on the chair with Drew's dog co-host, Douglas - who looked very comfortable, indeed.

When asked what it felt like to be 'cared for', Zoe replied: "It feels lovely — I have to say there were for many years when we first got married, it was hard for me to accept it because there's a part of us and women, you know, if our hearts have been broken before where we self-sabotage a lot."
