Kelly Osbourne has become a mother as she welcomed her first child with boyfriend Sid Wilson. But she seems a little upset at her own mother for revealing the news before her.

Her mother, Sharon, revealed the exciting news on her show "The Talk" on Tuesday.

"They're doing just so great. So great. She won't let a picture go out of him. I'm so proud of her," the 70-year-old said, adding that her grandson is named Sidney.

But on Wednesday, Kelly took to her Instagram page and seemingly called out her mother for sharing details about her son.

"I am not ready to share him with the world," the 38-year-old "So Undercover" actress wrote on her Instagram Story "It is no one's place but mine to share any information on my baby."

Kelly's father had also earlier slipped out details about her pregnancy. She confirmed in October she was having a baby boy after her father told "everyone" about it.

"I mean, he's told everyone...the gender of my baby before I ever got the chance to," Kelly said at the time. "And I'm just like, 'Aww Dad, come on. Like, come on,' but I will say, every single day he does this little song and this little dance about how excited he is, and he is so excited that it's a boy. It's the first — out of me and my brother, it's the first boy, so, he's like planning all these things."

Kelly said her father was having a hard time keeping the baby details a secret because of his excitement.

"Well, look, all I will say is that my dad has f------ told everybody because he's so excited," she said. "If you just look up one of his interviews, you'll find the answers. Even though I'm not saying anything! He did an interview today and I'm outside the door. I'm like, 'Dad, shut up!' He tells everyone because he's so excited."

The "Fashion Police" alum first announced she was expecting a baby with her Slipknot rocker boyfriend in May.

Kelly uploaded a selfie of her holding an ultrasound image and said, "I know that I have been very quiet these past few months so I thought I would share with you all as to why... I am over the moon to announce that I am going to be a Mumma. To say that I am happy does not quite cut it. I am ecstatic!"
