Caitlyn Jenner is going to star in an upcoming episode of 'Mrs. Brown's Boys.'

Caitlyn is due to appear on the sitcom that took away the best comedy prize at the recent National Television Awards.

'Mrs Brown's Boys' beat such favourites as 'Derry Girls', 'Fleabag', 'Sex Education' and 'After Life' to the award.

Folks are speculating that Jenner shot her cameo for the series while in the UK for the awards ceremony.

Caitlyn presented the Challenge Award to 'The Great British Bake Off' on the night and took to the stage alongside her 'I'm A Celeb' co-stars (Jenner was much loved during her stint on the reality series) when they won the Bruce Forsyth Entertainment Award.

It was herself who announced the news that she's going to cameo on 'Mrs Brown's Boys' via Instagram.

She shared a picture of her on set filming for the show alongside Brendan O'Carroll, who plays the titular mammy.

No word on Caitlyn's exact role in the episode revealed.

And we've yet to get an air date for the episode too.
