The reality co-stars didn't hold back when it came to the PDA after partying at TOWIE star Billie Faiers' In The Style bash in London on Thursday night (10 December).
Charlotte and Gaz put on quite display for the cameras (revealing quite a bit of tongue!) as they kissed passionately outside DSTRKT nightclub in the early hours of the morning.
After their songfest had finished, Char was picked up by a male friend… and ended up flashing her knickers to the paparazzi. Oops.
Charlotte, 25, and Gaz, 27, have been the hot topic of conversation this week after they were seen kissing in a SnapChat posted by their Geordie Shore co-star Holly Hagan.
It confused plenty of fans who thought Charlotte was dating Love Island star Max Morley, 22.
After the kiss, Max spoke out to say he was disappointed, telling MailOnline he felt Charlotte's actions were disrespectful. "I mean we were never official but I would never do what she has done to me. Charlotte is only Gaz`s little toy - good luck to her. She`s not all that - there is plenty more fish in the sea will, I have learnt my lesson - I will most definitely go for a more classy girl next time and hopefully I wont be used as entertainment."
Charlotte, meanwhile, posted a video to YouTube in which she said although she and Max weren't exclusive, she did feel guilty... until finding out he'd given an interview and then she became angry and said she was glad she kissed Gary.
So are Char and Gaz dating now?!
Gaz said on his YouTube channel: "We just needed to spend some time together with no cameras, no pressure, no one around us. It felt like a first date but it wasn't. Me and Charlotte are in quite a good place. We're both single and guess what, we're going to have a little bit of fun! There's no harm in that."
