Twin brothers John and Edward Grimes may have made their mark on the 2009 series of "The X Factor" (I mean, who could forget the time they served Britney Spears realness with their rendition of "Oops...I did it again" in matching red patent leather suits?), but it was in the "Eurovision Song Contest" that they made history. The singing duo marked the first time that Ireland sent the same act two years in a row, after they performed their track "Lipstick" in 2011, and performed again on the Eurovision stage in 2012 with their song "Waterline". They may not have won, but the pair were given worldwide publicity and are very much still in the public eye with their performances and extremely on-brand elaborate outfits. Oh, and you'll be pleased to know their gravity-defying quiffs are very much back, too.
