We're not sure whether the couples were pals before, but they certainly looked friendly as they joined each other for a few drinks at London's Radio Rooftop Bar.
Taking to Twitter, Luis made sure to let followers know who he and girlfriend Cally were rubbing shoulders with, sharing a snap of the group on the social media site.
In the photo, Luis is pictured sitting alongside Wayne and his Love Island co-star Naomi Ball as they joined Cally and The Saturdays' Frankie, along with her sister and friends.
Next to his photo, the reality star tweeted: "Radio bar with @MissCallyJane @naomi_ball @FrankieTheSats Wayne and friends."
Small world, eh!
While we're pretty sure pro footballer Luis was excited to meet former Reading player Wayne, it seems Frankie may have been the one behind the group's improptu get-together.
Just last week, Frankie revealed she was a big fan of Love Island, telling followers she was "gutted" the ITV2 dating show had come to an end.
"Gutted @LoveIsland is ending! I was so late to the party," she tweeted. "Yesterday's episode was amazing & tonight is not disappointing already! #hideandseek."
We're not sure who would have been more starstuck?!
Luis and Cally were one of the four couples to make it to Love Island's final after viewers watched love blossom between the pair.
And despite Luis and Cally not winning the show and pocketing the £50,000 prize fund, it seems their romance is still going from strength.
Since touching back down in the UK, the couple have been inseparable, with Cally telling followers she "falls deeper" in love with her boyfriend every day.
The couple had finished fourth on the show, losing out to Love Island winners Max Morley and Jess Hayes. Hannah Elizabeth and Jon Clark (who are now engaged!) came in second, with Lauren Richardson and Josh Ritchie taking third place.
Following the final, host Caroline Flack told fans she was "immensely proud" of Love Island and the show's success.
