Kelly Osbourne is going to be a mom! The TV personality revealed on Thursday, May 12, that she’s pregnant in an Instagram post showing a sonogram photo.

“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!” Kelly, 37, wrote in the caption.

It’s unclear when Kelly’s baby is due, but her sonogram photos were dated May 3. She shared a close-up photo of her growing baby, along with another snapshot of her lying on her stomach on a lounger next to her pool, gazing lovingly at the ultrasound shots. She was wearing a baggy blue blouse and along with her body position, it was impossible to see her baby bump.

Kelly did not name who the father of her baby is in her post. She was last romantically linked to Slipknot rocker, Sid Wilson, 45, going Instagram official with him on January 20 by sharing a cuddly photo of the pair and wishing him, “Happy birthday baby,” in the caption. Hours after Kelly’s announcement, Sid shared a close-up shot of the baby from Kelly’s ultrasound to his Instagram page with a caption featuring pink hearts as well as a family emoji featuring a dad, mom and child. He did not mention Kelly by name or tag her.

The pair were first photographed together holding hands on February 3, as they attended her brother Jack‘s daughter Minnie’s fourth birthday party. They arrived together in a black SUV along with Kelly’s mom, Sharon Osbourne, so Sid already appeared to be part of the famous family.

The former Fashion Police cohost gushed about finding her “soulmate” in a Valentine’s Day Instagram post. Next to a snapshot of the couple passionately kissing, Kelly wrote, “After 23 years of friendship I can’t believe where we have ended up! You are my best friend, my soulmate and I am so deeply in love with you Sidney George Wilson.”

Sid shared the sentiment, posting the same photo in black-and-white and writing in the caption, “There is not enough colors to display the palette of love I have for you in my heart. Happy Valentine’s Day my love XoXo.” While it’s unclear if the pair are still together, Kelly and Sid continue to follow each other on social media.
