BRITNEY Spears is not a fan of her “dumb” performance at the MTV Video Music Awards back in 2001, when she famously performed with a live python. The 34-year-old singer insists she would never repeat the risque stunt again, which saw her belt out her hit I’m A Slave 4 U dressed in nothing but a green bikini top, bejewelled shorts and the albino snake draped around her neck. “It’s insane! Why did I do that?” the mother-of-two told E! News while promoting her upcoming new single, Make Me.
