Roxy and Jack were said to have made their romance exclusive just before the UK went into lockdown in March.

Last month the couple sparked engagement rumours when Roxy could be seen wearing a gold ring on her wedding finger during an outing in Essex.  

When contacted by MailOnline, a representative for Jack said the couple are not engaged. 

Describing their budding romance, a source told The Sun earlier this year: ‘Jack and Roxy are enjoying being in isolation together. It’s all very new but they’re in their own little bubble and things are perfect at the moment.

‘Being on lockdown in a honeymoon period is certainly one way to get to know each other quickly. But the more time they spend together the happier they seem. 

‘Both have had their share of heartbreak and struggled a bit to find love. It’s time they had some luck.’

Roxy has a string of famous exes, having previously been linked to A-list actor Leonardo DiCaprio and singer Jake Bugg who she split from in December.

Jack has been linked to various women since calling it quits with actress Gemma Chan, 37, in December 2017 after six years together. She is now in a relationship with screen star Dominic Cooper.
