Evan Ross and Ashlee Simpson had a dance battle when they first met.

The 'Hunger Games' star has revealed the pair tried to show each other they were the better dancer on the night they first met.

She said: ''We met at my friend's birthday party. Evan walked in and he was really cute, and I was like, 'Who's this Mr. Cool Pants?'''

In a sneak peek clip of their new reality television series 'Ashlee + Evan', he added: ''You tried to dance with me. You were, like, lifting your leg up and stuff, trying to show me that you dance better than me, I think.

''We dry-humped a little bit. That was the best dry-humping I've ever done in my life. I put my best work in.''

Meanwhile, the couple recently insisted having cameras in their home wouldn't put a strain on their marriage.

Evan said recently: ''I think in any relationship in this industry, there's a stress on relationships. I think that's reality, but in no way do I think that if a relationship is meant to be together and a marriage is meant to be together, that anything like a show or being in this industry can change that. I don't think any fear is coming from our relationship, which is a good thing.''

And Ashlee is keen to add to her family.

She shared: ''I want one more. I definitely want to have another one, for sure. I love being a mom. I mean there's really nothing greater than my kids. So, for me, that's something I continue to want to do in life.''
