Emma Bunton's son is "in love" with Mel C's daughter.
The former Spice Girls singers spend a lot of time together, and have noticed a special friendship growing between two-year-old Beau and Scarlet, nine months.
Emma revealed: "I had dim sum at Mel C's with Mel B this week. While us girls had a chat, Beau spent the time hugging Mel C's little girl Scarlet. He absolutely loves her!"
Meanwhile, Mel has opened up about Scarlet - her first child with partner Thomas Starr - admitting she is "fascinated" by the tot.
She said: "I'm constantly astounded by her. I could stare at her for hours. She fascinates me. I find it incredible to think that she's part of me and Tom. It's impossible to explain how life-changing motherhood is."
Despite her joy, Mel is amazed at how exhausting she is finding motherhood.
She said: "Looking after a baby is the hardest job in the world. Doing the day job is a bit of a rest! I thought that I'd worked hard before - I lived on so little sleep in the Spice Girls - but nothing could have prepared me for being a new mum. It totally wiped me out.
"It was overwhelming at times. When the baby won't sleep and it's 4am and you're beyond exhausted, it can be lonely.
"Sometimes you feel like the worst mum in the world because you think that everyone else is doing better. I can see how easy it would be to flip into post-natal depression."
