Kelly Osbourne cradles baby bump as she joins Jada Pinkett Smith for Red Table Talk

Kelly Osbourne looked radiant as she cradled her blossoming baby bump while stepping in for Willow Smith on Red Table Talk.

The pregnant daughter of Ozzy and Sharon Osbourne temporarily took over hosting duties as she joined Jada Pinkett Smith on the show.

Kelly showed off her growing baby bump in a black dress which hugged her new curves in a show preview shared to Instagram.

The short teaser showed the 37-year-old, who announced back in May she is expecting her first child with Slipknot star Sid Wilson, walking towards the iconic table.

"Come out here, mom-to-be, Kelly Osbourne. Look at you," said an excitable Jada in the preview clip ahead of the full episode's release tomorrow.

Sporting her trademark purple hair, Kelly beamed as she joined Jada on the panel for the hit-Facebook talk show.

"So excited for Kelly! She wanted to be a mom for so long," said one fan. "Yay can’t wait she looks so good," added another.

Kelly has come full circle after, in a previous episode of Red Table Talk from June, she opened up about her desire to start a family.

"Yes, I feel very behind. As a woman, I would have loved to be married and have children by now," she said. "My brother [Jack] has three daughters and I would have loved to have kids by now, but that wasn’t what was in the cards for me yet."

Her show appearance comes after Kelly revealed that her pets have joined in bed ever since she became pregnant, making her "feel so protected" at night.

She shared a snap with her 2.4 million followers on Instagram of her pet pooches sleeping beside her. "Ever since I became pregnant all the dogs started sleeping in bed with me," she told fans. "I love it."

She added that the dogs "check on me all night". "I feel so protected," she said.

Kelly took to her Instagram in May to announce that she was expecting her first child with Sid.

Alongside a sweet snap of the expectant mum holding her baby scan, she said she was looking forward to being a first-time mum.

"I know that I have been very quiet these past few months so I thought I would share with you all as to why," she penned.

"I am over the moon to announce that I am going to be a Mumma. To say that I am happy does not quite cut it.

"I am ecstatic," she added.
