Grammy Award-winning pop singer Lady Gaga turned heads at Royal Albert Hall Monday night when she performed with Tony Bennett in a see-through dress at a charity fundraiser that Prince Harry attended. The concert was for WellChild, a charity supporting sick children. Prince Harry is a patron.

It is not the first time Gaga has worn an outlandish dress to meet a member of a royal family. In 2009, she almost showed up the Queen at a Royal Variety Performance at the Opera House Theatre in Blackpool when she arrived in red latex outfit.
