Singer Kelly Osbourne says she cried when her two-year-old niece Pearl told her she loved her.

Pearl - the daughter of her brother Jack and his wife Lisa - called her on the phone for the first time recently.

`She called me and told me that she loved me on the phone for the first time the other day and I burst into tears hearing that little voice going, 'Auntie Kelly, I love you.',` Osbourne told People magazine.

`I had tears just roll down my face.`

She is convinced Pearl is the `most incredible` child she has ever seen.

Osbourne said: `She is just the most incredible, incredible little bundle of joy and the most beautiful - she's so funny.

`I'm not just saying that because she's my niece. Even other people are like, 'I have a kid, but that kid's real cute.'`

The 29-year-old recently came in third place in a poll to find the auntie of the year.
