Sharon Osbourne. TV personality. Colon cancer survivor. Married almost 30 years to rock icon Ozzy Osbourne. Mother to Kelly and Jack Osbourne. And finally, at the age of 59, grandmother-to-be!

Son Jack and his fiancee', Lisa Stelly are expecting their first child in April, reports People.com. And Sharon says she couldn't be happier. "It just gets better and better, the thought of it, as we're getting closer and closer," she told a reporter for People last week.

Sharon says she warned the expectant parents that she's going to be "the grandmother from Hell" because of her plans to "spoil this baby so bad". And, as the 25th-richest woman in the UK, she certainly has the tools to do it!
