Derry Girls’ Sister Michael leads the lineup on tonight’s Ray Darcy Show

Staying in this evening? If so and you're a fan of Derry Girls, make sure to stick on RTÉ One.

Siobhan McSweeney, who plays nun Sister Michael in the hit Channel 4 series, leads the line-up on this week's Ray Darcy Show. Siobhan, arguably the show's breakout star thanks to her turn as the sharp-tongued nun, will join Ray to talk abut growing up in Cork and why she gave up a career in science to pursue acting. Also appearing on the show will be Coronation Street star Kym Marsh. She's set to spill the beans on her upcoming exit from the soap after 13 years as barmaid Michelle Connor and her role in ELF - A Christmas Spectacular, which comes to Dublin's 3 Arena this December. She'll also tell Ray about becoming a grandmother aged 42. Michelle's 22-year-old daughter Emilie gave birth to a son earlier this year. With the Rugby World Cup now in full swing, RTÉ pundits and ex-Ireland players Bernard Jackman and Stephen Ferris will be on the couch too. They'll be sharing their thoughts on the opening games of the tournament and looking ahead to Ireland's first match tomorrow morning. Wedding planners Tara Fay and Bruce Russell of RTÉ show My Big Day: At Home or Away are set to chat to Ray too while BBC Radio 2 DJ Cerys Matthews, who recently launched a new cookbook, rounds out the line-up. The Ray D'Arcy Show airs on RTÉ One at 9.55pm tonight.
