The pair are said to have hooked up after meeting on the E4 series, even if the point of the show was for the celebs to date 'normal' people.
In tonight's episode, at 10PM on E4, Joey is seen 'jokingly' asking Stephanie out on a date following their far from subtle flirting over the past two weeks.
According to the Daily Star on Sunday newspaper, Joey and Steph have in fact gone a lot further than a date since the show was filmed earlier this year.
"Joey and Steph have been inseparable all week and haven’t been able to keep their hands off each other," a source told the tabloid at the weekend. “Joey’s been staying over at Steph’s home in Chelsea. They are already making plans for Christmas and talking about meeting each other’s family.”
Speaking earlier in the summer, Joey played down rumours of a romance between the pair, saying: "We see each other filming sometimes, but that's about it really.
"She's a nice girl but we're just getting to know each other as friends."
Celebs Go Dating continues this evening on E4 as the stars go speed dating.
It's the final week and with only a handful of dates left, the celebs are getting thrown into the deep end. They get five minutes per person and are meeting old and new faces. Have they learnt how to spot true love in minutes?
Celebs Go Dating airs tonight at 10PM on E4 and continues each week night.
