Sharon Osbourne wants more grandchildren.

The 'Talk' star's son Jack and his fiancee Lisa Stelly welcomed their first child, daughter Pearl, into the world on Tuesday (24.04.12) and the proud grandmother is so besotted with the tot she ready for her two daughters Aimee and Kelly to have kids as well.

Sharon said: ''It's all overwhelming. But in a good way - in a really positive, lovely way. It's just amazing.

''I've got two more girls to marry off. There will be more grandkids!''

Jack's rocker dad Ozzy is just as thrilled to be a grandfather and had some fatherly words of advice for new parent Jack, 26.

Sharon revealed: ''[Ozzy told Jack,] this is a love that is so special. He said, 'You will never experience a love like this, other than a father and a daughter. It's a very, very special love.' ''

Sharon was in the delivery room when Pearl was born and she admits it was incredible to share the experience with Lisa.

During an appearance on 'The Talk', the 59-year-old star revealed: ''It's like a new life. There's nothing like it, to witness.

''You go through every emotion. You go through joy and you thank God that everybody is healthy and happy. You realise how lucky you are. It's like life has gone full cycle in our family.''
