Lady Gaga is in London! After spending the week with her boyfriend Taylor Kinney, who is currently on the set of a movie in Serbia, Mother Monster touched down at Heathrow earlier today and was greeted by a massive crowd of screaming fans outside her hotel.

Lady Gaga is set to play two sold-out shows at the legendary Royal Albert Hall with Tony Bennett on Monday and Tuesday nights. The Monday concert will benefit WellChild, a national charity working to support children and young people with complex health needs. 

"WellChild is thrilled that Lady Gaga and Tony Bennett are supporting WellChild through this concert," said a spokesperson for the charity. "The proceeds will be a massive boost to our work to support seriously ill children and their families across the UK."

It was announced earlier this month that Prince Harry, who is a patron of WellChild, will be in the audience.
