The Canadian singer split with husband of four-years, Deryck Whibley, in July 2010, and has since moved on with Kardashian step-brother Brody Jenner.
Appearing on Chelsea Lately, the 26-year-old said that she hopes to give marriage another go one day.
'It's all about love and I make that my number one priority,' she said.'One day I would hope to have kids and do that whole thing. Right now I'm very focused on my career, my album, my tour and naturally when that happens for me next, yeah I'll go for it.'
She added that despite their split, she is still close friend with ex-Whibley.
'We're not doing each other but yes, we're friends,' she said. 'I really respect him as a person and as an artist so it's all good.
'Deryck is very inspiring to me. He's so talented, and I really look up to him. I call him all the time, like, 'Yo, I've got a music question. Help me.' He has such a kind heart and he's so smart. We're there for each other.'
