Hayes said: "It's been such great fun working with Jedward and all the celebrities who gave up their time to make the video. I really enjoyed writing the song; it took me back to my old radio days, and hopefully it will raise a lot of money for the ISPCC. Come on Ireland, we can win it... maybe."
Jedward added: "We were really happy when 2fm contacted us and told us that Colm Hayes had written really cool new lyrics for Lipstick. The song is awesome!
"It's great to be involved with the ISPCC, and the Irish football team. It's the perfect song for Ireland to go to Europe with as all the other countries already know Lipstick so they will be able to sing along with it.
"We want all our fans to go out and buy it and pick up a cape in Elverys, and support the ISPCC. Get your green capes on Jed Fans!"
The official Jedward Green Capes are on sale in all Elverys stores nationwide at €4.99 each.
