In the villa the girls took a similar test and it ended in tears when Gabby confessed she didn't love boyfriend Marcel - which was apparently the truth.
"To be put in the spotlight was so hard," Gabby admitted today.
However the pair insisted that it made them a stronger couple.
On ITV's Lorraine today, Gabby was again put in the hot seat - but so was Marcel.
Both were found to be telling the truth when asked if they enjoyed one another's company and whether they thought wedding bells be in their future.
But there was another awkward moment for Gabby when she was asked whether or not she was a fan of Blazin' Squad and told she was lying after saying no!
Elsewhere on the show, on a far more serious topic, Gabby and Marcel spoke out against racist abuse.
The pair finished fourth in last Monday's live show and now on the outside, Gabby this week shared some shocking comments she's been receiving.
She said: "Right guys so I have been reading through some of the messages I’ve received over the past few weeks and I’m absolutely horrified at the amount of disgusting racial abuse due to mine and Marcel’s relationship.
“Its completely unacceptable and to know that this is still goes on in 2017, it breaks my heart.
"I’ve grown up in multi-cultural and LGBTQIA environments all my life.
"To know that this is still a thing, I’m mind blown.”
The dancer concluded: "There are some idiotic people in the world and they should be disgraced."
