Christina Aguilera talked babies with Lady Marmalade collaborator and mum-to-be Pink live on air in Los Angeles on Friday morning (19Nov10) when both stars phoned in to American Idol host Ryan Seacrest's radio show at the same time.
Aguilera congratulated Pink, who confirmed the news she is pregnant earlier this week (beg15Nov10) and then started quizzing her about her health.
The Beautiful singer asked, "How are you feeling? Do you have morning sickness yet?"
Pink replied, "I feel like if I had morning sickness, I would have lost some weight. I've kept everything down."
Upon hearing the news the baby is going to be a girl, Aguilera quipped, "She's gonna kick your a**," and then added, "We should have playdates."
Aguilera's son Max is two.
