The reality stars appeared on ITV's This Morning on Thursday (8 September) to discuss E4's Celebs Go Dating, where viewers watch a dating agency trying to find true love for famous faces including Joey and Steph.
But Holly and Phil were more interested in whether love had happened off camera, noting the pair's touchy feely behaviour and the fact they attended the TV Choice Awards together.
Phillip commented: "You guys looked like you were quite into each other so did a spark happen away from dating the public?"
"I'm shocked by this!" replied Stephanie, turning to look at Joey.
Joey, meanwhile, dissolved into giggles.
Holly told Joey: "You can't hide anything, what is going on?!"
Joey, who looked mega embarrassed, admitted the pair do go on a date in Celebs Go Dating but as for anything off camera, well, they were both keeping mum…
When quizzed if they had gone on a date since filming ended, Steph said: "I think we're still working on the show right now so that's hard to answer!"
"Yes, we have filming tomorrow," confirmed Joey.
Holly responded: "So will you give her a nudge and go into work together when the alarm goes off?"
They also noted that Joey had his hand on Steph's knee at one point!
While Joey and Stephanie are refusing to discuss their status, their Celebs Go Dating co-star Charlotte Crosby reckons there's definitely something there.
Chatting to Heat magazine, Char said: "I think Joey's really into her but Steph seems to be playing her cards close to her chest. She's, like, his ideal girl but she has her guard up and doesn't give much away.
"From the outside looking in, I would say that Joey is smitten, but I'm not so sure about her. I hope he doesn't get his heart broken."
On the latest episode of Celebs Go Dating, there did seem to be a spark! Joey and Steph went shopping together, where Stephanie seemed utterly bemused that Joey just stripped off on the shop floor to try on his clothing rather than going into a dressing room.
They've clearly been hanging around each other a lot, though, as Stephanie was able to decipher Joey's unique Essex lingo for Holly and Phil today!
Celebs Go Dating airs weeknights on E4.
