Super Junior's leader Leeteuk has showed his support for the rookie girl group SPICA.

On February 8th, the singer tweeted a photo of SPICA's album jacket and wrote, "Rookie group SPICA that even Hyori-noona likes!!!^^ Hyung-guk hyung whom I’ve known well since before debut, and came through Shinhwa, Kangta-hyung and SNSD, has now created an independent and talented girl group! Their mini album is out on 8th February!!! Hope they make it daebak!!!^^".
