Yup, the BFFs and co-hosts actually locked lips while celebrating Caroline's win at Cosmopolitan's Ultimate Women of the Year Awards.
AND Cazza posted the smooch on Instagram for us all to see. Is that her way of confirming she and Olly are now an item? What does this all mean?
Caroline had bagged herself the award for Ultimate TV Personality and told fans she was "so proud" she couldn't speak.
Of course, her bestie Olly was on her arm to help Caroline mark the moment, even presenting the 36-year-old with the gong on stage.
They then headed to the photo-booth to take some celebratory snaps, not only cosying up together, but kissing too. Taking to Instagram, Caroline shared their photo-booth photos for fans to see, but there was only one snapshot that caught the attention of her followers.
On seeing picture proof that the duo had kissed, fans were quick to share their thoughts.
One user commented: "WHAT AM I SEEING?? JUST FRIENDS?? MY LORD GUYS NO." While another said: "They must be together!?"
While most seemed all for the pair striking up romance, some weren't so convinced the smooch was genuine.
A fan struggled to believe Olly and Caroline's kiss was real, writing: "I think [they're] teasing us." While another joked: "He doesn't look like he's enjoying it."
Others, meanwhile, were just happy to see Caroline and Olly together - even if they are nothing more than besties.
"Together or not they have a beautiful friendship. Cuteness," said one. Another commented: "I think the public are forcing them to feel like they should get together. It would of happened by now if they were meant to be more than friends. well done for the award though :-) ."
Caroline and Olly's kiss comes after the pair have been putting on a very amorous display while presenting The X Factor live shows lately.
Just last week, Olly performed his new single 'Kiss Me' on stage and showered Caroline with kisses while she interviewed him after his performance. His PDA caused a stir on Twitter, with many viewers expressing their wish for the pair to become boyfriend and girlfriend.

Rumours of romance have been heightened between the pair ever since Caroline confessed her relationship with Olly was not "purely platonic".
She said: "It's a weird chemistry. We have the innate understanding of one another, we don't fancy each other and yet we don't not fancy each other.
"We're not girlfriend and boyfriend, yet we're not totally platonic either."
Sounds like it's a romance just waiting to happen, no?
