My grandkids call me Gaga, Camilla tells Lady Gaga!

CAMILLA arrived for the Royal Variety Performance in a stunning red ball-gown last night and met her namesake...Lady Gaga.

The Duchess of Cornwall told the US star how in her family she is not known as Grandmother but to young Prince George and the other children she is Gaga.

The Duchess, 69, attending with Prince Charles, also met Robbie Williams, Gary Barlow, Sting and Emeli Sande before the event at the Eventim Apollo, Hammersmith, London.

The Prince of Wales, wearing a dark dinner suit, appeared in fine form after sharing a joke with Robbie, 42.

The show, hosted by actor and comic David Walliams, will be broadcast by ITV next Tuesday.
