Mel B used to enjoy beans on toast with Princes William and Harry when they were teenagers.
The 'America's Got Talent' judge first met the 33-year-old royal and his older brother Prince William, 35, in November 1997 when she and the Spice Girls performed in South Africa, and a month later, the two princes were taken to the premiere of 'Spice World: The Movie' by their father Prince Charles.
And Mel, 42, revealed she and her bandmates used to also have private visits with the then-teenage princes.
Speaking about William and Harry, she told 'Entertainment Tonight': ''Oh, they're great. They're great kids.
''We'd go over to their house and have peanut butter and jelly sandwiches. And we would have beans on toast.''
Mel previously hinted she and the rest of the Spice Girls would be performing when Harry marries Meghan Markle later this month.
She said: ''I'm going. I don't know if I should've said that. Us five Spice Girls did [get an invitation]. Why am I so honest?''
Mel wouldn't divulge what the invitations to the big day looked like as she felt that was ''too personal'', but talk quickly moved on to whether or not the band would be performing at the reception after the couple have officially tied the knot.
The star didn't verbally confirm the news, but once the question was asked she threw her cue cards into the air, and added: ''I swear I'm just ... I need to go, I'm going to be fired. I'm gonna be fired.''
However, her bandmate Mel C later insisted her pal was joking.
She said: ''I've met Prince Charles lots of times. I'm going to ask him where my invite is because I haven't got mine yet, obviously Mel B said she has hers. I think Mel was just kind of having a bit of a joke. There are no plans to go to the wedding at the moment.''
