It's no secret that Mrs Brown's Boys is hugely popular, both in Ireland and the UK, but two of the show's stars told Mairead about another very high profile fan!
Fiona and Eilish O'Carroll stopped by the studio ahead of their two Christmas specials, and advance copies of the episodes have been requested every year by none other than Queen Elizabeth herself!
They also chatted about when Brendan O'Carroll came by to see Mairead's school production of Joseph and the Amazing Technicolour Dreamcoat and had some lovely words of encouragement for everyone who took part.
