Kristen Bell had to compete for husband Dax Shepard's attention in a dance-off during their date night at a roller disco.

The 'Bad Moms Christmas' star and her spouse Dax were joined on their ''couples skate'' date at the Moonlight Rollerway skating rink in Glendale, California at the weekend by pal Ryan Hansen, who co-starred with Kristen in 'Veronica Mars'.

Dax posted a video on Instagram of himself dancing with 'Frozen' star Kristen and Ryan and asked his followers: ''Which dance partner did it better? @hiryanhansenor @kristenanniebell?!''

Kristen, 37, also shared footage from their night out, joking: ''Incredible night at @officialmoonlightrollerway- not a single broken bone!''

The couple - who married in 2013 - are parents to daughters Delta, two, and Lincoln, four, and were clearly enjoying some couples time without their kids.

Kristen has previously revealed their children have walked in on them having sex.

Speaking on 'The Talk', the blonde beauty said: ''Oh, they've walked in on us having sex. That's how they were made, it's OK!''

When Julie Chen asked what she and Dax did, the actress said: ''Well, we didn't, like, continue ... we sort of just went like, 'Hey, what's up? What do you need? What do you need?'... And then we just said, 'Mommy and daddy are just going to take a nap for a couple of minutes.'''
