The 'Simple Life' star had nine-year-old daughter Harlow in fits of giggles as she recorded her mom dancing to Bobby Darin's 'Splish Splash' whilst she helped the reptile enjoy his first bath.

Captioning the video, which she uploaded to her Instagram account, Nicole wrote: "Speedy had his 1st bath this weekend & it was a blast ... even in a room full of haters #splishsplash #letmelive (sic)"

In the video, Harlow - who Nicole has with her husband Joel Madden - can be heard telling her mom she's "embarrassing" Speedy the lizard.

Meanwhile, Nicole - who also has Sparrow, eight, with Joel - previously revealed she thinks it is important that her children have a "full-blown childhood".

She said: "Well, for Joel and me, it's very important. And it's just been this way since day one. It's extremely important to us for our kids to be kids, to have a full-blown childhood. And that is the life we've created for [them]. Not that there's anything wrong with taking your kids here and there, and sometimes we do and that's really fun, but family and togetherness and just developing a strong closeness and trust with our kids right now, especially at this age, is the most important thing to us. So, that is where we spend most of our time.

"We are a few years away from my daughter being a teenager. Now is the time for me to really have some one-on-one time with her, for me to hang out with her friends, to do things that she's interested in. And what we both do is just try and pour our interest into what the kids are interested in. We ask them what they want to do. And if it's going to a movie, we just try to keep it enjoyable. And by the way, I like to do that. I like to go to the mall - it's fun ... going to Dippin' Dots!"
