Jack Osbourne's fiancÃ© Lisa Stelly has given birth to a baby girl.
Weighing in at 8lbs 6oz, the little one has been named Pearl by her proud parents, according to Hello! magazine.
The couple - who announced their engagement last September after a four-month romance - were expecting their first-born to arrive last Wednesday (20.04.12).
Taking to twitter on Tuesday night (19.04.12), Jack said: ''Well @lisamarstelly is supposed to give birth to our baby tomorrow. Fingers crossed.''
But by Friday (22.04.12) there was still no progress when Lisa tweeted: ''Still pregnant. Apparently I made too lovely of a home int here! #overit #comeonbaby. (sic)''
Jack's sister Kelly was just as eager to meet her niece, and already has plans for girlie shopping trips.
Sharing her thoughts on the pregnancy, she said: ''I don't have the words to express how excited I am about it. I'm so proud of Jack and Lisa. I couldn't stop crying when I saw the ultrasound of their baby girl.
''Jack loves his privacy and he's turned out to be one of the most respectful, well-rounded and honest gentleman around. The two of them are going to make great parents.
''I can't wait to style my niece. I've already told him I'm going to steal her and take her out shopping.''
