Emma Bunton's son thinks there is a Flexible Spice in the Spice Girls.
The 37-year-old star - who is known as Baby Spice in the group - is bemused as to why her six-year-old son Beau has made up a member of the girl band who he calls the "Spicey Girls".
Emma isn't totally sure who Beau is referring to, but assumes it must be Mel C due to her Sporty Spice nickname.
She exclusively told BANG Showbiz: "Beau calls us the Spicey Girls because he doesn't quite get it and he thinks there is a Flexible Spice.
"I don't know who that is supposed to be? I thought possibly Mel C as she is Sporty!"
Emma - who achieved worldwide pop success in the Spice Girls alongside Victoria Beckham, Geri Halliwell, Mel B and Mel C - says Beau's favourite group is One Direction, but he loves playing his mother's music at home.
The blonde beauty - who also has a two-year-old son Tate with fiancé Jade Jones - revealed: "Beau is a big fan of the Spice Girls. He's definitely a big One Direction fan, too. I think he has to be with all the girls in his class constantly singing their songs.
"He loves Olly Murs and he loves Robbie Williams as well so he generally likes good music."
