We pondered the strange wording of Caroline Flack’s sarcastic tweet to ex-boyfriend Jack Street last week, and now it seems that she was dropping a heavy hint at the true reason behind their split.

When Jack appealed to his social media followers to vote for Caroline to make it into the final of Strictly Come Dancing, the former X Factor host accused him of trying to ease his guilt over their split and told him to ‘fill himself with glee’.

Now it has emerged that the 35-year-old may have been making a reference to former Glee actress Dianna Agron, whom it has been revealed has been getting very close to Jack while he works with singer Sam Smith in the States.

Dianna starred in the video for Sam’s song I’m Not the Only One, and rumour has it that she and Jack had a lot of fun partying together – something which Caroline only recently found out about.

“Caroline didn’t know Jack was at those places and only found out later though friends,” a source told The Sun.

Something tells us the drama has only just begun!
