Kelly Osbourne takes the plunge in a low-cut top and black biker jacket as she attends Cupshe pool party in Beverly Hills

Kelly Osbourne put on a busty display as she attended the Cupshe Pool House event on Wednesday.

The podcast host, 39, was first spotted walking down the sidewalk outside the party venue in Beverly Hills.

She looked phenomenal in a low-cut black bodysuit styled with light wash denim jeans.

Kelly — who is mom to an adorable baby boy — layered up with a classic black biker jacket with shiny silver hardware.

She paraded around in a pair of sky-high black open-toed heels with a Chanel purse over her shoulder.

Kelly wore her icy blonde hair in a curly ponytail that she secured in place with a black ribbon.

As for makeup, the former E! Fashion Police host opted for a bronze smokey eye and a matte pink lip.

Once inside the invite-only event in LA, Kelly posed in front of a large swimming pool with a Cupshe display behind her. 

Cupshe is an affordable and stylish brand with inclusive sizing that offers shapewear, swimwear and other closet staples for women.

The Bachelorette's JoJo Fletcher, Selling Sunset star Amanza Smith and pregnant model Iskra Lawrence were also on hand for the event in Beverly Hills.

Kelly's outing on Wednesday comes amid the success of The Osbournes Podcast - the podcast she hosts with rockstar dad Ozzy, mom Sharon and younger brother Jack.

The show — who delves into the family's personal lives, Ozzy's stardom as well as their takes on hot topics —  re-launched in late 2023 following a five-year hiatus.

On the June 4 episode, Kelly spoke candidly about her past substance abuse and joked that it's 'pickled' her body.

'I'm hoping that I've embalmed myself so I don't ever get cancer,' she said, before adding lightheartedly: 'I'm pickled from all the drugs and alcohol, for sure.'

Jack, 38, warned, 'I don't think it works that way. But I'm no doctor.'

It was also mentioned that colorectal cancer runs in their family — mom Sharon Osbourne, now 71, battled the illness in the early 2000s.

'Apple doesn’t fall too far from the tree,' Kelly noted.

An ER doctor named Dr. Greg was a guest on the latest installment of the show, and jokingly added: 'I, for one, have never heard of substances you put into your body causing ill effects of any kind.'

This isn't the first time Kelly has discussed her experience with addiction. 

In 2021 she revealed on the Facebook series Red Table Talk that it started with an opioid prescription when she was just 13-years-old.

'I kept getting sick and I had a really bad case of tonsillitis, they ended up having to give me some crazy surgery, and then after that, they gave me Vicodin.

'And that was all I needed,' she recalled.

Kelly explained further, 'I went from having every voice in my head being like, "You're fat, you're ugly, you're not good enough, no one likes you, you don't deserve this, people only like you because of who your parents are."

'And then all of a sudden, every single voice was silenced and it felt like life gave me a hug.'

Kelly went on to say, 'I was like, "Why am I so confident in all of this?"

'And then very quickly I went from Vicodin to Percocet, from Percocet to heroin eventually, because it was cheaper.'

In 2021 she told Extra about a brief relapse: 'I am an addict and had thought that I had enough time under my belt and I could drink like a normal person, and it turns out I cannot and I will never be normal.

Along with being a successful podcast host and TV personality, Kelly is busy being a devoted mom to her 19-month-old son Sidney with musician boyfriend Sid Wilson, 47
