DERRY GIRLS actress Síobhán McSweeney is recording Christmas messages for fans – and raising money for charity in the process. The Aherla native, who shot to fame for her role as Sister Michael in Derry Girls, has joined Cameo “for a limited time” ahead of Christmas Day. The actress, who is also known for her role in the telly adaption of Graham Norton’s novel HOLDING and for presenting THE GREAT POTTERY THROW DOWN, said she gets “so many requests for video messages” so she decided to join the platform for a limited time and raise money for charity in the process.
