Timberlake: Smith family reaction my favourite part of Miley twerking routine

Justin Timberlake's favourite part of Miley Cyrus' controversial MTV Video Music Awards routine was Will Smith's shocked reaction.

The 32-year-old singer didn't see any problem with the 20-year-old singer's heavily-criticised saucy performance, during which she 'twerked' and gyrated over Robin Thicke while wearing a miniscule nude-coloured bikini as the pair performed his 'Blurred Lines' hit .
