Victoria Beckham — better known as Posh Spice of the Spice Girls — has disclosed that her husband, British soccer star David Beckham, likes to slip into her undies. To wear them, that is. “He likes to borrow my knickers,” she said on British TV’s “Big Breakfast” program. She then quickly insisted that she was joking. Interviewer Johnny Vaughan pressed her further, though. “I know you’re not joking,” he said. “Is it thongs or big pants?” “Thongs,” she whispered. Beckham is currently in Rio de Janeiro where his team, Manchester United, is due to play in soccer’s inaugural World Club Championships. No word on what he is wearing under his uniform.
