Roxy looked sensational in a frayed black dress which had edgy zipper detailing on the front that reached the ensemble’s plunging neckline.

The blonde beauty styled her locks in a sleek, straight style that fell over her shoulders in a side-swept style, while she used a natural palette of make-up.

She completed her look by carrying her personal items in a large black handbag, and she accessorised with a gold pendant earring. 

Jack made sure to follow his fashionista girlfriend’s styling tips, as he wore a black button-up shirt and trousers with white trainers.

‘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.
