The "Late Night" host introduces her to some of his signature cocktails, before serenading her with one of her own songs.
He kicked off the fan-favorite segment by downing a shot and a full beer in one gulp before introducing his guest. Then, as Rihanna started chugging her own beer, he told her, "You don't have to do that."
And while she didn't drink nearly as much as the "Late Night" host did for this segment, the singer did hold her own against him, and even took on some of his most horrific concoctions inspired by her music.
Meyers was giddy behind the bar as he introduced her to drinks like Under My Rumbrella, We Found Vueve In a Hostess Place, and Bitch Better Have My Bunny. And if you thought champagne and Hostess Twinkies were an odd mix, you're not alone.
That said, Rihanna was all about that last drink, which was as simple as pouring tequila into a headless hollow chocolate bunny.
They filled their afternoon with a drinking game where Rihanna had to try and identify where she wore some of her most iconic fashion looks, and Seth really thought he had her with the last one. "This one I'll be very impressed if you can get right," he told her, but the response was immediate.
"Dentist," Rihanna shot back, which led to a lot of cursing and, well, drinking.
Later, the duo took turns offering sage bartender advice to one another with Seth suggesting a counter career for Rihanna should she ever give up music (and all of her other business ventures), while she went very, very dirty with her advice for him.
"I want to blow my wife away with a romantic night out. What should I do?" Seth asked.
"You said it," she said simply, but Seth didn't get what she meant. Let's just say when she clarified it, he immediately chastised her, shouting, "This is a network television show."
Finally, it was makeover time and after lots and lots of alcohol, how could this go anything but smashingly?
Seth asked Rihanna for a "summer eye" with her Fenty line, and what he got was more reminiscent of "Avatar." But it was enough that he exuberantly -- and terribly -- serenaded Rihanna with one of her most romantic songs.
"Work, work, work, work, work, work," he sang. "You see me I be work, work, work, work, work, work."
