A preview picture for Wednesday evening's (18 March) episode shows Lewis planting a kiss on Gemma while attending the cast's St. Patrick's Day party.
With no further information available, we have no idea what's going on!
And Gemma and Lewis are keeping us guessing with their teasing tweets today!
Gemma shared the picture of them kissing on Twitter, alongside the caption: "It started with a kiss #towie #lewisbloor #GC_2015 is back." She also added two heart emojis.
Lewis, meanwhile, simply said: "Romance is in the air in tonights #towie you lot."
Oh, we're intrigued!
