The boys will appear at the Donegal store at 4pm. Local store manager Eamonn McLoughlin has made plans to have all the twins' favourite movies in stock on the day!

RTÉ will be attending the Letterkenny appearance by the twins, as they're filming a documentary called Jedication which will air later in the year.

The duo will also have appeared at Xtra-Vision's Parkway SC store in Limerick on Monday July 19 at 11am.

Since the X-Factor, the Grimes brothers have sold out their recent Irish Tour, and are now set to release their latest single 'All the Small Things'.
