And finally the translation is:
His best piece (of clothes)

Bill Kaulitz (18) is Germany’s most diverse singer! He always wears the newest outfits and the most trendy hairstyle. But the Tokio Hotel-Frontman simply couldn’t give up from one piece: from his white-red-blue leather jacket! Beforehand in January, 2007 he has already wore this in a Bravo Photoshoot, now he digged out his best piece onto the TH-appearance in the ’Rock in Rio’ Festival in Lisbon, Portugal. No wonder: this piece is simply mega cool!
