Mrs. Brown's Boys returns for their annual Christmas special, which will also be accompanied by a New Year episode to help us celebrate 2024.

Brendan O'Carroll reprises his role as the foul-mouthed Irish matriarch Agnes Brown, who is known for her volatile yet hilarious relationships with her children.

Brendan tells us: "When I was a kid it wasn’t Christmas until we watched Morecambe and Wise and had a supper of leftovers — turkey and stuffing sandwiches and Christmas pudding! It was the highlight. The fact that Mrs Brown now has that slot is absolutely unbelievable and a huge, huge honour.“

Here's everything you need to know...

The Christmas special is titled Mammy's Mare. With Cathy cooking Christmas dinner, a sentimental horse ornament going missing, two last-minute guests and an Australian-sourced tree, this festive visit to Finglas has more jokes than a Christmas cracker factory. In the opening scenes, there's a chill in the air as (brave!) Cathy (Jennifer Gibney) kicks her mum out of her own kitchen but, before the credits roll, Agnes (Brendan O’Carroll) is rocking around the Christmas tree in delight. A feast of funny with a side order of sentimentality, this seasonal special manages to be both bawdy and heart-warming (no mean feat). Knees up Mother Brown! 

Meanwhile, New Year, New Mammy sees Agnes and co attempting to start 2024 off right with a health and fitness routine, but how successful will it be? If laughter is the best medicine there's a healthy dose of comedy on show here (and some rather fetching shell suits!) as Mrs Brown and the gang turn their attention to getting fit for 2024. The Blubber Club is formed, with no-messing Maria flexing her authority and keen Cathy leading the charge. Looking for something to lighten up the mood it isn't long before Agnes and Winnie are distracted by a blast from their past — a former flame called Larry (Kin star Aidan Jordan) seems eager to get Winnie’s heart racing. Will Mrs B tell him to jog on?
