Kelly Osbourne Says There Was 'No Adjustment Period' to Becoming a Parent as She Praises 'Mom Life'

Kelly Osbourne is loving every part of mom life.

The 39-year-old star attended Dolly Parton's Pet Gala event in Nashville, chatting with Entertainment Tonight about how she's bonded with her 15-month-old son Sidney over his first year of life.

"Mom life is the absolute best," she tells the outlet. "There was no adjustment period for me because I love it all. The good, the bad, the ugly, I take it all. It's so much fun."

"It's given me a purpose in life like nothing ever has," Osbourne continues. "Just getting to watch my little man grow and seeing him become a little person is just, like, it's gonna make me cry if I keep talking about it."

As he's getting older, Osbourne is discovering her son's personality, as well as his likes and dislikes.

"His favorite food is cheese. He loves all kinds of cheese and he'll sometimes eat so much cheese that he smells of cheese," she jokes.

Osbourne shares her son with her Slipknot musician boyfriend Sid Wilson.

Last month, Osbourne shared a photo on Instagram from the event, which showed her and son Sidney hanging out with Parton.

"Oh my God, I have died and gone to Dollywood!!!!!!! Here is a little preview of our day with @dollyparton and about 100 dogs. It was literal heaven," Osbourne wrote.

"It was such an honor to be asked by Dolly to be a part of such a wonderful Gala. Thank you again, Miss Dolly, we had the absolute best time!!!! More pictures to come. #Dollyspetgala."
