“Gilmore Girls” characters Luke and Lorelai have reunited for the first time since 2016 … in a new Walmart ad.

Scott Patterson (Luke) and Lauren Graham (Lorelai) acted in the commercial alongside Sean Gunn as Kirk — set in the show’s iconic town square and Luke’s Diner.

In the themed commercial, Kirk walks through the town square past a town troubadour to enter the diner with a special delivery for Luke, Us Weekly reported, and Lorelai enters the diner after Kirk exits, saying “Coffee, coffee, coffee please!”

“Coming right up,” Luke says as he puts a blue Walmart box in front of her, which turns out to be a gift for Lorelai — a Keurig coffee maker.

The gift is par for the course for Lorelai, his coffee-obsessed wife in the show, People reported, and he joked she’s “drinking him out of business” in the ad, which lasts 30 seconds.

The Walmart ad ends with Lorelai encouraging viewers to purchase gifts from the retailer, Us Weekly said.

“Gilmore Girls” aired from 2000-07 for seven seasons, and Luke and Lorelai finally tied the knot in the 2016 Netflix revival series “Gilmore Girls: A Year in the Life.” In the ad, Luke can be seen wearing a wedding band, according to Us Weekly.

“It’s always a little surreal (returning to Stars Hollow) because we were back where we’ve been so many times,” Graham said to People, adding that filming the ad nostalgic. “It was a particularly odd day for me because there’s just so much familiarity with that character and seeing Scott and being in that place.”

Patterson said working alongside Graham again was the highlight of doing the Walmart ad, as she’s his “favorite scene partner of (his) entire career.”

“I’ve never worked with anybody with a better skill set, more grit and just this incredible stamina among the other things that she brings with her humor and her kindness,” he told People. “I’ll always cherish the time I got to spend with Lauren and act with her because she’s literally an icon.”

The Walmart ad has sparked conversation online among “Gilmore Girls” fans, who have been hoping for more episodes after the 2016 revival.

Other users talked about character Jess Mariano’s stint as a Walmart employee of the month in the fictional show, saying Milo Ventimiglia should’ve returned for the commercial as well.

Graham and Patterson said the potential for more episodes is in the hands of creator Amy Sherman-Palladino and her husband, Daniel Palladino, People reported.

“I wouldn’t even venture a guess how they would do it or what it would look or feel like, but I’m sure it would be fantastic in every way,” Patterson said.
