Is Caroline Flack upset over her ex Jack Street moving on so soon after their split?

Caroline Flack has caused concern amongst her fans by posting a very emotional Instagram post.

The TV star, 35, shared a cryptic message accusing a mystery person of ruining her day, which was a pretty big one as it was the first screening of her debut as a presenter on The X Factor.

She wrote: ‘When someone who knows you more than anyone ruins the biggest day of your life’

Alongside the upset message is a photo of Caroline admiring a glitter ball that she holds in her hands.

Caroline’s followers were quick to send their best wishes to the presenter, with one commenting: ‘Are you ok?? I love you so much, don’t let anyone drag you down ❤️❤️’

Another wrote: ‘keep your chin up – you are amazing and don’t let anyone make you think otherwise!’

It’s been speculated that Caroline’s words could be aimed at her ex-boyfriend Jack Street, who she split from for a second time earlier this month.

The music manager was seen hanging out with a girl in a photo posted by Sam Smith during a trip to Ibiza this week and Caroline is said to be upset that he’s apparently moved on so quickly after their break-up.

A source tells the Mirror: ‘Caroline is heartbroken to see him move on so fast. She thought they could make a go of it the second time. Clearly it’s over now.

‘This break-up has been even more acrimonious than the last. And the timing of him going public with a new girlfriend couldn’t have been worse.

‘She has been gearing up for the X Factor launch for months. All she wants is for it to be a success and she felt she didn’t need the drama.’

Whatever the reason behind Caroline’s heartbreak is, we’re glad to see that her pals are helping her through it.

The former Strictly Come Dancing champ stepped out with Olly Murs at the X Factor TV series launch last night in London and showed her appreciation for him in an adorable Instagram post later in the evening.

Cazza shared a picture of the duo together on the red carpet and wrote: ‘When your friends are brilliant … X’

Awww, keep your chin up Caroline!
