We Are Young Fun.
Dozens of fans queued outside Waterstones in Midsummer Place to meet Sharon Osbourne on Friday.
She was there to sign copies of her novel, Revenge.
But fans had a longer wait than expected. Ozzy Osbourne's wife got stuck in traffic and was almost two hours late for her appearance.
Staff at the book shop gave the waiting fans chairs to sit on and sweets to keep them going.
