Lady GaGa performed her single 'Judas' at the Cannes Film Festival yesterday (11.05.11).

Despite the 'Bad Romance' hitmaker's record-breaking 'Monster Ball Tour' concluding in Mexico last week the singer hasn't stopped performing, appearing onstage at the event in a Matador styled black and gold outfit, which was completed with a red cape much like that used by bullfighters.

On stage Gaga was flanked by a number of backing dancers semi-clad in black and gold Romanesque style clothes and the live show, which was witnessed by a select crowd, was filmed for French TV show 'Le Grand Journal'.

The 25-year-old singer took to her twitter page to write about the experience, tweeting: "Just performed in Cannes for Le Grand Journal. Amen, Magdalene Fashion! Thank you for supporting me!"

Earlier in the day, Gaga rehearsed for her appearance clad only in black lingerie, tights, studded leather boots and a huge black and white wig with a stark fringe.

Gaga's hectic schedule has seen her perform at the Robin Hood Foundation Annual Gala in New York City at the end of last week, before jetting to Europe.

She is scheduled to play a secret show in London tonight (12.05.11), ahead of an appearance at the Radio 1 Big Weekend festival on Sunday (15.05.11).

She tweeted this morning: "Just landed in London, so happy to be back in UK."
