Leona Lewis and Michael Lane perform on ‘The Voice (Germany)’.

Leona Lewis thrilled fans of ‘The Voice (Spain)’ earlier this week and she followed that showing by appearing on its sister series in Germany. Once again, the diva joined forces with one of the contestants, Michael Lane, for a rendition of her hit song ‘Trouble’.

Unfortunately for Lane, he couldn’t quite find the right key and he was easily out-shined by Lewis, who soared through the arrangement of ‘Trouble’. Lewis did try to warn him that she was trouble but he just refused to heed her warning. Watch them perform on ‘The Voice (Germany)’ below:
