The 26-year-old posted a picture onto her Instagram account, posing with Jeremy with the caption ‘We appreciate all the love and the hate’.
Photos have also circulated of the couple kissing on a yacht near Turkey earlier in the week.
Chloe is the heiress to Philip Green, who is the chairman of Arcadia Group, which owns various retail stores including Topshop, Dorothy Perkins and Outfit.
The fashion expert originally found fame as a star of Made in Chelsea when she joined during its second series.
However, in the end she only stayed on the show for a few months, leaving before the third series began.
Before joining the Made in Chelsea, Chloe was already in a relationship with fellow MIC star Ollie Locke back in 2011.
She has also previously dated American singer Marc Antony, and has been linked in the past with Lucien Laviscount, Fazer Rawson and even Chris Brown.
Chloe’s father Philip Green recently made headlines after the closure of BHS, which saw around 11,000 people lose their jobs.
Following the controversial collapse of the retail chain, Philip agreed to pay over £360m of his own money to rescue the BHS pensions.
