"Game night had all the drama," Nick, 42, captioned the video.
The video featured newlyweds Joe Amabile and Serena Pitt, who were all smiles, before the camera panned over to Victoria, who had her arm around Greg at a dinner table in someone's house.
Victoria, who smiled at the camera, then gave Greg -- who competed on Katie Thurston's season of The Bachelorette in 2021 -- a sweet little kiss on the cheek.
Fans are currently watching Victoria pursue a relationship with Johnny DePhillipo on Bachelor in Paradise's eighth season. The pair have actually professed that they're "falling in love" with each other.
But for those fans who have been following recent Bachelor in Paradise spoilers, Greg and Victoria's display of public affection isn't a surprise.

According to Reality Steve spoiler blogger Steve Carbone, Victoria and Johnny continued dating for the rest of Paradise.
After enjoying a Fantasy Suite, Victoria and Johnny made it all the way to the finale and got engaged.
One of the men Victoria had allegedly cheated on Johnny with is Greg, who was slammed for how he dumped Katie on The Bachelorette 17 and was accused of gaslighting and being an aspiring actor.
Johnny added to the rumor mill by posting on his Instagram Stories how he's "unwell," but Victoria's BIP pal Sierra Jackson recently tweeted, "My girl doesn't cheat! None of my ladies do."
Victoria is reportedly dating Greg now, and the couple were spotted in Italy together on multiple occasions -- and by different fans -- late last month.
After BachelorNation.Scoop uploaded a video of Victoria and Greg in Italy on October 28, Victoria commented, "Mind ya damn business."
Reality Steve spoiler blogger Steve Carbone was also able to confirm Victoria and Greg were on a European adventure together, which included stops in Capri and Rome.
Shortly after the video surfaced, Greg posted a flirtatious "good girl" comment -- which he quickly deleted -- on one of Victoria's Instagram posts, which showed the brunette beauty posing in a sexy black dress with cut outs.
Carbone tweeted on November 5 that Victoria and Greg were talking pre-Paradise but it was nothing serious. Victoria allegedly claimed at Bachelor in Paradise's reunion taping that she told Johnny about this.
But Johnny allegedly caught Greg texting Victoria post-finale, after Johnny and Victoria got engaged and had their phones returned.
"She assured him she & Greg were just friends. Johnny found out [through] social media about the Italy trip," Carbone tweeted.
According to Carbone, Greg will appear on the reunion special with Victoria to confirm their new relationship.
Greg and Victoria also reportedly got a matching tattoo -- the word "hot" in Italian -- on their arms while they were in Italy.
Bachelor in Paradise's two night finale is set to air on Monday, November 21 and Tuesday, November 22 at 8PM ET/PT on ABC.
