Donny & Marie Osmond

Singing siblings whose partnership has sustained two TV shows (one of the late-'70s variety, one '90s talk), but whose ticket-pushing power obviously depends most on the self-proclaimed 'Puppy Love' victim and dentally impressive '70s heartthrob Donny. Nevertheless it was Marie who got them in the headlines (and into our good books) lately when she giggled so much on stage that she literally wet herself – yes really, and to the extent that a towel had to be called for to mop up. The lady just carried on laughing – respect!
