Carrie Bickmore turns up the heat in very revealing activewear as she steps out in Melbourne with her teenage son Ollie

Carrie Bickmore turned up the heat on Wednesday when she was spotted enjoying a sunny day in Melbourne with her teenage son, Ollie.

The veteran presenter, 43, showcased her slender figure and youthful appearance in very revealing black and white activewear.

Carrie rocked her best angles in a black, figure-hugging exercise singlet paired with skimpy white gym shorts and matching sneakers, highlighting her well-toned arms and long, slender legs.

The radio host accessorised with stylish sunglasses and added a touch of glamour to her look with a gold necklace and hoop earrings.

Her blonde hair flowed freely around her shoulders, and she opted for a makeup-free look, which accentuated her radiant natural beauty.

The upbeat media personality appeared to be engrossed in conversation with her 17-year-old son as they made a coffee run to a local café.

Carrie looked to be in great spirits as she walked down the street, and with her youthful appearance and flawless complexion, she could easily pass for a woman half her age .

Carrie and her Fox FM co-star Tommy Little have repeatedly been hit by romance rumours ever since they hosted their HIT radio show from Paris, France , last year.

Last month, the pair were spotted cuddling up for a photo behind-the-scenes at the ACRAs.

The drive show co-hosts skipped the red carpet at the radio awards and snuck in through the kitchen together.

They stopped to pose for a picture in the bustling backroom, with Carrie turning heads in a very short black dress.

Carrie split from her partner of 11 years Chris Walker at the start of 2022 , while Tommy has been reportedly single ever since his split from girlfriend Natalie Kyriacou in 2021.

Tommy rushed to Carrie's side at the time she confirmed her break-up, leading insiders to speculate their friendship could evolve into something more.

Carrie announced her split from Chris in an Instagram post in January 2022, saying they were focusing on co-parenting their children, Ollie, Evie, nine, and Adelaide, six.

'It's with immense sadness Chris and I have decided to separate. While this is a tough time, our focus is on supporting our children,' Carrie wrote.

Elsewhere, the pair have had a hugely successful year with their drive time radio show, Carrie and Tommy - in August, it was named Australia's number one national drive show.
