Appearing on Fallon to promote her involvement in Dumplin, Dolly shocked the TV host as she recalled her husband's reaction to her latest project.

'My husband is crazy about her,' she told the host. 'He was more excited that I was going to do a movie with her than he was that I got the chance to write all this music. See, I think he kinda fantasizes, like, a threesome with us.'

Jimmy was left speechless, before pointing to the camera and joking: 'Go to bed Carl!'

Dumplin' was helmed by Anne Fletcher, whose previous directorial efforts include 27 Dresses, The Guilt Trip, The Proposal and Step Up.

The script was adapted from Julie Murphy's novel by Kristin Hahn - a bridesmaid at Jennifer's wedding to Brad Pitt.

Netflix announced this September that they had picked up the movie, which was filmed during the second half of last year in Georgia.
