No Perez Hilton: Lady Gaga and Perez Hilton have long been firm friends - until he criticised her 'Applause' single online. The star later accused the celebirty blogger of stalking her, suggesting she was under threat of being shot in the head when he was spotted by a fan at her apartment building. She wasn't, he was just looking for a new flat. Nonetheless, he won't be making a trip to the UK for the show - guaranteed.
