Sharon Osbourne has shared a saucy bathtub shot with fans, shortly after confessing her sex life with husband Ozzy Osbourne is thriving.

Soaking in a marble hot tub, the showbiz couple could be seen covered in suds as they splashed about in the tub, with Ozzy's, 71, tattoos on full display through the soapy water.

Setting the mood, candles in crystal cut vases surrounded the lavish tub, and an ornate mirror cast reflections of the nude hot tub endeavour.

With both pulling a funny face in the saucy throwback snap, Sharon, 67, urged her fans to embrace their "sense of humour" when scrolling past the Insta snap.

She quipped: "I'll just be here looking for everyone's sense of humor... #itiswhatitis."

In the comments below the photo, Sharon's fans were quick to praise the couple's famously outgoing personalities, as one wrote: "This is why I love you."

"Omg sharon yall are literally icons," added another, while a third penned: "Love you Sharon! Stay true to yourself. People are ridiculous! Your family is the best!"

The starkers snap comes after Sharon spilled the beans on her sex-life with Ozzy, opening up on an episode of the US series The Talk.

Sharon revealed the showbiz couple tends to hit the bedroom twice per week

Sharon, who is a regular panelist on the daytime discussion show, was grilled by her co-star Sheryl Underwood, who asked: "How many times a day are you and Ozzy getting it?"

Sharon replied: "We all know we oversexed, it's not secret. He had enough for all... he liked to share."

She added: "It's getting less. It used to be three times a day, but it's much less now. Let's say a couple of times a week.

Sharon and Ozzy walked down the aisle 38 years ago, and share three kids

"Which is normal in a long, long relationship."

The lovebirds have been married since 1982, and have raised three children together over the years – Aimee, 37, Kelly, 35, and Jack, 34.

In January, Ozzy revealed he had been diagnosed with Parkinson's disease, a neurodegenerative disorder that progresses slowly in the majority of sufferers.

Describing her husband's condition, Sharon admitted it was up and down, as she told Good Morning America: "There's so many different types of Parkinson's; it's not a death sentence by any stretch of the imagination, but it does affect certain nerves in your body.

"And it's – it's like you have a good day, a good day, and then a really bad day."
