Mila Kunis is allegedly upset with Demi Moore. Ashton Kutcher's former wife is supposedly trying to give parenting tips to the 33-year-old actress, who gave birth to a baby boy on 30 November.

The celebrity couple who are already parents to daughter Wyatt Isabelle Kutcher, recently welcomed a son, Dmitri Portwood Kutcher and Moore reportedly sent presents to the newborn baby. A source told Radar Online: "Demi has been trying to butt in Ashton and Mila's lives again after the baby was born by bringing by gifts and trying to give Mila advice on how to raise more than one kid."

"But Mila just snapped and told Demi that she has had enough. She wants her to just leave them alone. Demi didn't have any boys anyways, so Mila seems to feel like her advice is just quite comical," the insider added.

"Mila is done playing nice to Demi and she knows that it might hurt her, but she is tired of pretending that they are friends. She's just over it," the source continued.

Meanwhile, Kunis had opened up about the things she would do for Wyatt and she will go to extreme levels to help her out. She told Business Insider: "I think if she killed someone, I would literally be like, 'I got it'. 'Where do you want me to bury the body?' I wouldn't even question it. I can't say that about anybody else in my life."

She added: "Everything is different. From the fact that you're so happy when you get six hours of sleep to the idea of being responsible for this incredible, living breathing little human being that you can't believe is yours."
