The pair sparked new romance rumours after dining out on V-Day, and now we've seen pictures from Jordan's Snapchat showcasing their romantic night out.
Marnie, who was previously engaged to TOWIE star Ricky Rayment, couldn't stop smiling as she and Jordan cuddled up for a selfie.
Jordan captioned the selfie "Valentine's" with two red heart emojis on either side.
Ibiza Weekender and Ex On The Beach star Jordan revealed his V-Day plans on Twitter, telling fans on Sunday: "It's time for #IbizaWeekender but unfortunately I can't watch it tonight due to Valentines plans with @MarnieGShore."
Keeping coy, Geordie Shore star Marnie replied with a blue heart and a kissing emoji.
Jordan and Marnie have actually been romantically linked before. They were rumoured to have been exchanging flirting messages last month, but Marnie apparently lost interest after hearing rumours about Jordan hooking up with Vicky Pattison and kissed Ashleigh Defty.
Now, however, has Marnie changed her mind?
