Interestingly, Beckham was said to be the most famous member of Spice Girls, reported Aceshowbiz.
"They used to turn it off and just let the others sing," Beckham, 42, recalled. "I got the last laugh and now my mic is well and truly on, finally."
She went on saying that she was "always much more reserved than the other girls" when performing their dance routines.
"When all the other girls were being fun and spontaneous and jumping on tables, I was always the one checking the table wasn't going to collapse," Beckham said.
The interview came weeks before Spice Girls will celebrate the 20th anniversary of their 1996 breakout single, "Wannabe".
The ladies are expected to reunite for a tour, which Beckham has said multiple times she won't be a part of.
