1994: Michael Jackson and Lisa Marie Presley PDA alert

The King of Pop and the daughter of the King of Rock 'n' Roll kicked off the 1994 festivities by welcoming the crowd and then locking lips for the longest, most awkward five seconds ever. This was amid rumours that their three-month marriage was a sham and the slobbering smooch was panned by critics as a ploy to clean up Michael's post-child-molestation-accusations image. Lisa Marie later told Rolling Stone: 'That was not my idea, by the way. I was terrified. It was his manager's idea. I thought it was stupid. All of a sudden I became part of a public relations machine.'
