Caroline Flack has revealed she knew almost instantly that her fiancé Andrew Brady was 'the one'.

Caroline recently shocked fans when she took to Instagram to confirm her engagement to CBB star Andrew after just three months of dating.

Now the presenter has revealed she knew he was 'the one' after just two days of knowing each other.

‘It was pretty instant,’ she told The Sun when speaking about her relationship.

‘I think it was the second day we met! It sounds really weird and at the time I thought, “No, don’t be silly brain. Go back in your shell”, but when I look back on it that feeling hasn’t changed.’

This comes after Caroline addressed the age-gap between her and Andrew.

"You can’t help who you make a connection with," Caroline – who's 11 years older than Andrew – previously told the Mail on Sunday.

"My mum says we seem like best mates – and that’s all I want."

Same, tbh.

Caroline broke the news of the engagement on Instagram when she posted a snap of her and Andrew showing off a sparkling ring on her wedding finger.

Caz captioned the photo: "He’s put it on my finger and it won’t come off ... so I’ve said yes. #chooselove"

However, just a couple of months earlier, the lovebirds' whirlwind romance seemed to be over for good, following claims Andrew had cheated on Caroline during a PA in Chester.
