Romance continues to be in the air in “Geordie Shore: Big Birthday Battle,” as Gary “Gaz” Beadle and Charlotte Crosby get more serious about their relationship. After a romantic date – their first official one in five years – things seem to progress positively between the two lovebirds.

However, it is Marnie Simpson who seems to be taking intimacy to a whole new level, as she discusses wedding bells with her on-and-off lover. On May 31, Aaron Chalmers gets the shock of his life when a nightcap turns into marriage plans. Fans are wondering what happens to the other cast members of “Geordie Shore,” including Team Charlotte’s Daniel Thomas-Tuck , Holly Hagan , James Tindale , Marty McKenna and Nathan Henry, as well as Team Gaz’s Chantelle Connelly , Chloe Etherington , Jay Gardner, Ricci Guarnaccio and Sophie Kasaei.

MTV has posted sneak peeks [watch below] of the reality show’s fourth episode, which is due to air on Tuesday night. In one of the preview videos, Aaron calls Marnie from their room to ask her out. The two hit a snag last episode, when he went totally out of control and ravaged the house. As a result, Marnie’s team lost by a point. “Aaron wants to lie low this morning, and I'm buzzing that he wants to do it with me so I'm going to make it my mission to cheer him up,” Marnie says in the video.

Whilst having a drink, Marnie takes Aaron by surprise. “I literally adore you. I honestly think that I am the perfect girlfriend,” she tells him. “What do you like about us? What do you want?” Aaron is clearly caught blindsided and he doesn’t mince words once he faces the cameras. “F---ing hell Marnie, I only came out for a pint and a cheeky neck on, not a f---ing relationship quiz,” he snarls. However, he doesn’t leave Marnie hanging and replies, “I said from the beginning I want to be with you.”

It seems to be what Marnie wants to hear, and she says, “We waited so long to have sex, that when it eventually happened I literally wanted to marry you.” To the cameras, Marnie reveals, “I'm so pleased that me and Aaron are on the same page, maybe this time things might finally work out between us.”

Whilst Marnie seems to fool herself into thinking that things are getting more serious between them, Charlotte is anxious about Gaz’s true intentions. In another sneak peek, Gaz and Charlotte sneak off to have some privacy from the others and snuggle in a double bed.

Gaz says he’s feeling “mortal,” and tries to charm Charlotte’s pants off with a striptease. However, he doesn’t get the reaction that he wants. “Gary I don't think you're serious,” Charlotte says. Gaz claims, “I couldn't be more serious! I'm giving you my all!” To the cameras, he further gets honest. “ Charlotte the fact that I'm just seeing you, surely that means I just like you. What is so hard to believe?” Charlotte seems to be worried what happens to them when they leave the “Geordie Shore” house. Gaz reassures her by saying, “Well then, we’ll get serious and then you’ll be my girlfriend.”
