Back in Dublin for a three-night run in the O2 with fellow X Factor finalists, brothers John and Edward filmed a 30-second promo in the Donnybrook branch of Abrakebabra, which will air on Irish screens from mid-April.
PR Joanne Byrne, who represents Abrakebabra, said the company were "excited" to have Jedward as the stars of their 30-second TV advertisement.
"You couldn't have someone more popular than John and Edward at the moment," she said.
Abrakebabra are the latest Irish company to be associated with twin brothers John and Edward Grimes.
Last December, Jedward brought chaos to Dublin's Henry Street when department store Arnotts used them to launch their St Stephen's Day sale.
Phone company Vodafone have also associated themselves with the twins, who come from Lucan in West Dublin.
Next Tuesday, Jedward begin their own 27-date Irish tour starting in Castlebar with all 35,000 tickets for the shows sold out.
Bono: No tweet on the horizon
Is it or isn't it? That was the question on Twitter this week when someone called '@bonopaulhewson' signed himself up.
Singer Neil Diamond was among fellow tweeters sending best wishes.
The Diary hates to disappoint everybody but after a quick call to U2's PR, we were told: "Whoever it is, it's not him. Bono is definitely not on Twitter."
However, something which is the real deal is http://peterrowenphoto.blog spot.com/ -- which is the personal blog of Peter Rowen, who featured on the cover of U2 albums Boy, War and the Best Of.
