British pop star Robbie Williams is giving fans a chance to get last-minute tickets to his upcoming London shows by launching free passes into the air.

The Angels hitmaker is releasing 1,000 red and yellow balloons from a secret location in the U.K. capital on Thursday (06Jun13) and 20 will have pairs of concert tickets attached.

Williams has posted photos of the special balloons on his Twitter.com page, writing, "Good luck finding one of these lucky Samsung competition balloons when they hit the sky in London."
