The commercial, which also features a cameo appearance from Sydney Sweeney, was shot at the same table in Katz's Deli where the classic 1989 rom-com was filmed.

It's time to return to Katz's Deli with the stars of "When Harry Met Sally" – this time though, it's for a Super Bowl ad

Meg Ryan and Billy Crystal recreated a classic scene from "When Harry Met Sally" for a new Super Bowl ad, with a special appearance by Sydney Sweeney.

The two actors revisit an iconic scene from their legendary romantic comedy in the commercial, a nostalgia play titled “When Sally Met Hellmann’s” (watch below). Ryan and Crystal play friends whose connection turns romantic in the 1989 movie written by Nora Ephron and directed by Rob Reiner.

Super Bowl 59 kicks off Feb. 9, but commercials featuring celebrities have already started rolling out in snippets. Brands pay big bucks to get their clips, which often have some of the hottest Hollywood talent available star in 30 seconds to a minute’s worth of a commercial.

Billy Crystal and Meg Ryan have reunited for the 60-second ad 'When Sally Met Hellmann’s,' as they recreate the famous Katz Deli scene from 'When Harry Met Sally.'

It was so much fun,” Crystal told The Post of reuniting with Ryan more than three decades after their iconic 1989 rom-com.

When I opened my Instagram feed and saw a picture of Meg Ryan and Billy Crystal together again, my first reaction was "AH!" — especially since they're sitting on a couch, just like they do at the end of When Harry Met Sally.

Super Bowl LIX is already proving to offer serious star power, with ad spots led by Chris Pratt, Eugene Levy, Michelle Rodriguez and even a When Harry Met Sally reunion with Meg Ryan and Billy Crystal.
