The 42-year-old star recently reconnected with Emma Bunton, Geri Horner, Mel C and Victoria Beckham to work on unspecified new projects and though they haven't announced their plans yet, 19-year-old Phoenix - Mel's eldest child, who she has with ex-husband Jimmy Gulzar - knows whatever they do will be ''fun''.
She said: ''I'm really excited, it's going to be fun. I'm excited for anything that's going to happen.''
The 'America's Got Talent' judge was joined at the Kids Choice Awards in Los Angeles by all her children, Phoenix, 10-year-old Angel - whose father is Eddie Murphy, and six-year-old Madison, who she has with ex-husband Stephen Belafonte, and the producer's daughter Giselle Belafonte, 14.
And the youngsters had nothing but nice things to say about the 'Mama' singer, with Giselle describing her as the ''funniest person'' she knows, and Phoenix simply saying her mom is ''cool''.
Madison said: ''She's beautiful! And nice.''
Angel added: ''She's always there for you if you have a problem.''
Meanwhile, Mel confirmed the Spice Girls are ''all back together'', but stayed tight-lipped on reports they are working on an animated superhero film about girl power.
She teased to 'Entertainment Tonight': ''I don't want to confirm that, but there's a lot going on.''
And though she recently hinted she and her bandmates are to perform at Prince Harry's wedding to Meghan Markle in May, she refused to be drawn on the subject.
Asked if she's going to the celebration, she said: ''I can't answer that.''
She then swiftly changed the subject when asked if she'd seen the news invitations had been sent out.
While Mel recently hinted the group will be performing at the wedding, her bandmate Mel C later insisted her friend had just been joking.
They'll hit the UK and Ireland this November.
