On her 45th birthday, Celine Dion gets drunk and starts to brag about her singing abilities. She turns to Katy Perry who is present at her party, and tells her, 'I'll sing the shit out of you, girl, anytime!'
Katy becomes very annoyed at Celine, plants herself in front of her with her hands on her hips, and replies, 'I'll take the challenge, let me hear it!'
Celine laughs, then says, 'It's a deal, you stupid brat! Tomorrow. In my private gym in the basement of my house! OMG, I'll so trash you and shit on you, you stupid loser!'
Katy tells Celine, 'That'll have to be seen, won't it, you ugly old hag!'
Celine, now furious, suddenly slaps Katy's face hard. Katy is stunned for a moment at the woman's outrageous behaviour then slaps her back.
The to women stare at each other, then agree on a three part contest of a singing competition with one of Katy's songs, arm wrestling, and a full on wrestling match on the mat in Celine's basement gym.
'At least your childish songs are easy to sing even for yourself, aren't they?' Celine says as a final dart at Katy.
'Just shut your fucking mouth, you ego inflated turd!' Katy hisses at her.
The two furious ladies part, only to meet up for their contest on the following day...
CELINE DION: 45 years, 5'7", 56kg, 34A
KATY PERRY : 29 years, 5'8", 59kg, 32D
