Jason Donovan has described his collapse at Kate Moss' 21st birthday party as "through the roof embarrassing".
The 57-year-old actor/singer was among the famous face who gathered at the notorious Viper Room venue in Los Angeles to celebrate the model's milestone back in 1995 with Kate's then-boyfriend Johnny Depp organising the bash and invited stars including Michael Hutchence, Christy Turlington and Linda Evangelista.
