Kelly Osbourne plays dress-up with niece

Kelly Osbourne is elated to find a "fashionista" comrade in her niece Pearl.

The Fashion Police star's brother Jack welcomed daughter Pearl, his first child with Lisa Stelly, on April 24 last year. He and Lisa tied the knot a few months later in October.

Kelly spends a lot of time with her niece and family matriarch Sharon also showers her granddaughter with love as frequently as possible.

Kelly couldn't get enough of seeing Pearl elated over the dresses she and her mother Sharon bought for the little tyke.

"Look how cute my little #Fashionista of a niece Pearl is with all her new beautiful clothes my mum & I got her!" Kelly gushed via Twitter.

Apparently Monday was a celebratory occasion on all fronts.

Kelly was happy to celebrate her in-law Lisa's new age.

"To my beautiful sister in law @MrsLisaOsbourne …!!! Happy Birthday!!!!!" she wrote attaching a humorous YouTube video of Tiny the Cat singing a Funny Birthday Song.

It appears the Osbourne clan has been enjoying a lot of crooning recently.

While dining over the weekend baby Pearl had a song dedicated just for her.

"At a ladies lunch with my niece Pearl who is currently being serenaded! She loves the piano man!" Kelly shared.

Only close family and friends were in attendance at Jack and Lisa's wedding last year.

Kelly served as a bridesmaid and mom Sharon turned 60 during the Hawaiian getaway.
