Lady Gaga wears mouse ears and dogtooth leotard

It appears no one can take Lady Gaga's crown for the most outrageous outfits, as she debuted another bizarre ensemble on the streets of the capital on Saturday.

Making her way to a sound check at the Roundhouse ahead of her performance at the iTunes festival on Sunday, the Applause singer wore head-to-toe dogtooth print.

The 27-year-old was greeted by hoards of fans as left her hotel in another classic outfit on the fifth day of her London trip.

Wearing what can only be described as black, mouse ears , the star teamed her unusual headwear with an eye-catching print leotard.

Gaga, who is no stranger to flashing a bit of flesh, took a more modest approach by teaming the skintight number with a white shirt.

The singer's tiny waist was accentuated with a wide gold and black belt.
