Just when we thought we'd seen it all from Lady Gaga, the pop star has turned up on German telly in her most bizarre dress yet.

The risque star is as famous for her crazy costumes as for her music, but even hardened fans were left gobsmacked when she appeared in a dress covered in dozens of Kermit the Frog replicas.

One of the Kermits also seems to have been given her trademark super-long eyelashes.

It is not clear from the film whether the outfit is a stage costume, or simply what Lady GaGa wears to relax backstage, perhaps German-speaking readers can enlighten us?
