The former X Factor star recently split from Melanie Sykes, according to reports.
Now it is being claimed that the Troublemaker singer is in Simon Cowell's bad books, and that the pair haven't spoken for months, despite working together closely in the past.
Olly is believed to have left Simon furious when he joined X Factor's rival show The Voice.
Of course, Olly shot to fame under Simon's wing back in 2009, and even had a stint presenting the series in 2015 with Caroline Flack.

In October, the cheeky chappy confessed that Simon had been silent since signing his new contract, insisting he doesn't believe in rivalries.
However, now the Up singer has revealed Simon still hasn't been in touch.
Olly, 33, told TV Times: "I have no idea if he's happy or not.
"I'm so proud of what I did on my X Factor journey from the early days up to now."
Where are these X Factor stars now?
