Posh Spice reunited with the girl power pop group for a world tour in 2007 and 2008 but has since made it clear she won't be returning to the stage with her former bandmates.
And singing pal Melanie Chisholm recently confessed she was a little upset when Beckham even refused to pose with the group at the launch of the Spice Girls stage musical in London last year.
Now, Beckham who has become a leading fashion mogul, has revealed she has no wish to perform again.
The singer is quoted by German publication ICON as saying, "I will never do it again in a professional way."
Instead, she's happy being part of the audience when her kids perform at home: "We are a very musical family, we sing and dance at home, the boys attend the school choir, play the guitar, (daughter) Harper likes to listen to songs from Little Mermaid and, like all mums do, I sing along with the kids in the car."
