Behati Prinsloo has been craving watermelon.

Speaking on The Tonight Show with Jimmy Fallon about her pregnancy cravings, he said: "She's eating a lot of watermelon. A lot of watermelon. Because, you know, they get random cravings for stuff and it's just like, so much watermelon! ... I eat a lot of stuff. A lot of stuff."

Meanwhile, the 37-year-old musician previously admitted he is really looking forward to the birth of their little girl and can't wait to spoil his 26-year-old wife Behati too.

He gushed: "It's awesome. I'm going to be a dad. S**t, I'm excited. I'm going to be a f***ing dad. I'm going to spoil Behati ... Kid's not even out yet. Can't be spoiling a kid before a kid gets out."

And Adam insists he is completely "ready" to have a child because he feels he was "born to be a parent".

He added: "I'm ready to be a dad. You're born to be a parent, that's what we're here for, really. All the other s*** is great, but it's not what we're here for."

However, the couple are desperately trying to ignore most of the advice they have been offered as they want to bring up their child in their own way.

He shared: "When you are doing this for the first time, everybody loves to tell you what you should be doing. So, we're kind of tuning a lot of it out and we're just going to do it how we do it."
