Remember these two from the X Factor? Jedward have been rehearsing for the Eurovision song contest in Duesseldorf, Germany.
The energetic twins are representing the Republic of Ireland with a song called Lipstick. Nice outfits lads.
Jedward have got their usual trendy hair styles but which one's John and which one's Edward?
The UK's being represented by four-piece boy band Blue, who are singing a song called I Can. Wonder if they'll be jumping in their performance?
The first Eurovision song contest semi-final will be on Tuesday, 10 May with the second semi-final on Thursday, 12 May and the final on Saturday, 14 May.
