Earlier this year, Rosie was said to be dating musician Miles Kane - and it appears they could still be in a relationship.
This weekend, Rosie was pictured with Miles while out for the day with best friend Millie Mackintosh and her husband Professor Green - aka Stephen Manderson.
The foursome had headed to a farmers' market, believed to be Hilly Fields in south east London, and Millie snapped them while at a burger stand.
Sharing the photo on Instagram, she commented: "Burger gang @professorgreen @rosiefortescue @mileskane."
MIC star Rosie was first linked to Miles in December 2013, however they were actually introduced to each other last summer.
Former Rascals and Last Shadow Puppets musician Miles is a good friend of Professor Green's, which is how they met, and she was even said to have flown to Paris to support him at a gig.
In the latest series of Made In Chelsea, however, Rosie has been portrayed as single and ready to mingle with good friend Louise Thompson.
After hooking up with New Yorker Alik, Louise introduced Rosie to his good friend Jules and they began hanging out together. But last night, Rosie was faced with the 'bombshell' that Jules is polyamorous.
On hearing the news, she blasted: "I just want to know why you failed to tell me that you have three girlfriends? I would chop your d*ck off if I had kissed you or even liked you...and you kind of make me feel sick."
She added: "You can do what you like in your personal life and private life, that's your issue, just do not involve me in your slutty board game unless you're truthful from the word go."
