Correction: Hyatt confirms that the Andaz Masonic Temple hosted Lady Gaga, while HELLO assigns the photo shoot to Gaga and the accommodation detail to Beyoncé. The assessed Gaga stay is corrected to an event; a separate overnight stay is not established or disproven.
The evidence connecting Lady Gaga to Andaz London Liverpool Street supports a photo-shoot event in the hotel's Masonic Temple, not the assessed overnight stay. The hotel's official Hyatt page confirms that the venue hosted Gaga, and HELLO's coverage identifies her activity there as a photo shoot.
