"I play the role of a realtor; the scenes are beyond hilarious"
She'll play an estate agent in an Irish special of It's Always Sunny In Philadelphia.
The Gang Goes to Ireland is due to air in the US on Wednesday.
"It's definitely a special episode within the entire 15th season, which now officially becomes the longest-running comedy series ever," Sonya tells the
"I play the role of a realtor; the scenes are beyond hilarious. I was directed by Megan Ganz who produces Modern Family and The Last Man On Earth to name a few, and also by the ridiculously funny Charlie Day who plays Charlie Kelly on the show."
Sonya (41) is based in Los Angeles with her musician husband Colin Devlin and their young children Evie and Leo.
"I'm such a huge fan of this show so it goes without saying I'm very proud and honoured to be part of this specific episode and to work with such brilliant comedians. The cast and crew were the most incredible, gorgeous, brilliant folk and I'm so delighted that I've had a chance to work with them. Get ready for some serious laughs."
The series follows the exploits of 'The Gang', a group of narcissistic friends who run the Irish bar Paddy's Pub in south Philadelphia, and includes many Irish-American and Catholic stereotypes.
The episode was filmed earlier this year in Ireland with stars such as Rob McElhenney, Kaitlin Olson, Charlie Day and Glenn Howerton coming here.
But it appears their co-star Danny DeVito, who plays Frank Reynolds in the hit series, may have given Ireland a miss as producers cast here for a DeVito lookalike.
Sonya made her acting debut in RTE series The Clinic, which was followed by a recurring role in The Tudors.
