The reality TV star, 33, has had a well-publicised on-off love affair with Arg - but it would appear that Gemma may still have feelings for her cuddly co-star...
In the seventh episode of the current series, due to air on Sunday 16 March, Gemma confesses to friends Sam Faiers, Ferne McCann and Jess Wright that she has a secret about her and Arg.
In preview pictures released by ITV2, the TOWIE girls can be seen looking shocked, while an embarrassed-looking Gemma tries to hide her face.
We can't wait to hear what the secret is... Although we think we can guess - naughty, naughty Gemma!
While her cosy chat with the girls seems pretty harmless, Gemma's mood turns sombre when she meets Arg later that day.
Enjoying evening drinks, Gemma gets emotional when Arg tries to talk to her.
The singer can be seen wiping away a tear from Gemma's face... Is she still harbouring feelings for him?
Meanwhile, all seems to be forgiven between James Lock and girlfriend Danielle Armstrong as the Essex lovebirds appear cosy in bed - despite Bobby getting more intimate updates from James' alleged fling.
And James' rumoured infidelity has also left poor Jess Wright feeling low.
In a heart to heart with Elliot - isn't he lovely? - Jess admits that the James / Danielle situation has opened up old wounds about Ricky Rayment's past betrayal. When Elliot questions her about their relationship, Jess breaks down in tears.
Elsewhere in Essex, Mario Falcone attempts to train Chloe Sims' dog, and Diags and Fran Parman thank Tom Pearce for bringing them together.
TOWIE continues on Sunday 16 March at 10pm on ITV2.
