Speaking on the first episode of the second season of The Osbournes podcast back in September, Osbourne celebrated her little boy's budding personality.

"He's gonna be such a naughty little boy," Osbourne squealed, delighted. "He's funny. It's weird to me how I look at him and he's like 18 weeks old and he does things that are just really funny."

She was also happy to share that Sid "loves his nana" Sharon, 70. "He goes and sees nana every morning and every night before bed and he just sits there laughing and chuckling."

"I do silly voices for him and he just loves it," Sharon explained. "He's very smiley with me."
