Simon Cowell collapsed after being hypnotised by a dog on entertainment show Britain’s Got Talent.

According to The Sun, Cowell “slumped over his desk” after staring into the eyes of a German Spitz called Princess.

During an audition at the Lowry Theatre in Manchester on 30 January, the 55-year-old music mogul climbed on stage to go eye-to-eye with Princess after her owner claimed that the dog could hypnotise people simply by holding eye contact.

After returning to his seat, Cowell reportedly told his fellow judges that he “felt strange” before collapsing during a break in filming.

Princess reportedly had to be called back on stage to wake Cowell from his slumber, in what an insider told the paper was “the freakiest moment we’ve ever had”.

Previously, presenters Ant and Dec were reportedly made to forget the number seven after being hypnotised by the dog.
