Pink is already planning playdates for her newborn daughter even though Willow Sage Hart is less than a week old.
The Raise Your Glass singer - whose real name is Alecia Moore - and motocross racer husband Carey Hart welcomed a baby girl Willow Sage Hart into the world last week and while former 'Charmed' star Alyssa has not yet given birth, the two stars are already hoping their kids will be friends.
Pink tweeted: "Alyssa_Milano enjoy this miracle, woman. I'm so excited for you. playdates are as fun to plan as bbq's used to be. Hahaha (sic)"
Pink's daughter could soon have more than one child of Alyssa's to play with as the 38-year-old actress recently said she was enjoying her first pregnancy so much, she is planning to have more kids as soon as possible.
Alyssa - who is married to David Bugliari - said: "I've had such a great time being pregnant that you're probably going to see me more pregnant than not in the next few years because I'm really digging it."
The actress has revealed she is expecting a boy, because she says she is terrible at keeping secrets.
She said: "As fun as it was reading all of your gender predictions on twitter, I'm really bad at keeping secrets and had to share (not to mention, I was bound to unintentionally slip at some point).
"David and I are elated to announce that we are having a baby boy. We can't wait to meet him. Boys names, anyone?"
