Congratulations, Kirstie Alley!

The 64-year-old is celebrating her recent 50-pound weight loss — thanks to Jenny Craig — and she’s doing so with the help of her Cheers costars John Ratzenberger and George Wendt in a hilarious new commercial!

"When the Jenny Craig people asked me [if I] would I do this, I said, 'Well, yeah, but is the set gonna look real?' And they assured me the set was gonna look fantastic," she said during a Today show appearance on Tuesday.

She continued, “When we walked on that set it was like a cross between The Twilight Zone and we were in a time machine, you know? But to see those guys sitting there, funny as ever — I'm sort of the straight man in the commercial, but that's okay! They get the jokes, and they should. But it was like we were right back in it. In fact, I thought, 'Why don't we just do this again? It would be fun.'"

Did Kirstie just hint at a Cheers reboot?! Our fingers are crossed!
