There were big celebrations in the Osbourne household this weekend as Jack Osbourne and wife Lisa marked their daughter Pearl's fourth birthday. In honour of the special occasion, Lisa shared a very sweet message for her little girl on Instagram, alongside a close-up photo of Pearl smiling.
"Four years ago this special girl was born and my life completely changed the instant I saw her gorgeous face," she wrote. "Those were my first words, 'She's so beautiful', as I sobbed.

"Everyone that knows her knows how special and loving she is. She has such an amazing personality and verbalises her emotions so well. She really is the light of my life & I am so lucky to be her mum. Love you Pearly girl."
The night before Pearl's birthday, Lisa was hard at work decorating a cake for her daughter – and later shared a photo of her very impressive creation, which was based on a character from the Shopkins children's toys range.

Jack, 30, and Lisa, who have been married since October 2012, are parents to two little girls, Pearl and her little sister Andy Rose, born 13 June 2015. They proudly introduced their new arrival in HELLO! magazine, just a month after she was born.
"We feel really lucky," Jack told HELLO!. "Pearl is such an awesome kid and we can already tell that Andy's amazing.

"It's the weirdest thing when you already have one child, who you love so much. I look at Pearl and I think, 'How can I have this twice?'"
Lisa added: "With the first, it's instant. You've created the best kid ever. The second child it's like, 'Hang on, I have an amazing kid already and I don't know you yet.' Every day Andy gets bigger, I love her more and more."
