Kelly Osbourne can't contain her excitement about the prospect of becoming an aunt.
The star's brother Jack, 26, is expecting a child with his model love Lisa Stelly and Kelly has already had a sneak peek at the unborn baby.
She tweeted: "Oh my God! I just saw a 3D sonogram pic of my brother's baby.
"I can't stop the tears of joy. The baby looks perfect! Proud Auntie."
TV star Jack announced in September that he was engaged to Lisa after dating for just four months.
He later revealed that she was pregnant with their first child.
"I'm about to be a father. I'm excited. I'm a little nervous, but I'm excited. It's going to be fun," he said at the time.
"I'm not going to do a reality show, though."
