ET met up with Sofia Vergara and David Beckham on the set of their new Diet Pepsi commercial.

The two playfully recalled their meeting each other in past instances and the soccer star commented on how it was amazing to work with the actress.

"We're a huge fan of the show so it's definitely great to work together," David mentioned. "She's amazing."

While the jovial banter between the two continued, the "Modern Family" star raved about David's acting skills. "It was great because he's very natural," Sofia quipped. "It's like we're not acting so it's easy."

Sofia also reminisced on the Pepsi commercial she shot 21 years ago when she was 17. "At that time I was doing regular Pepsi, now I'm doing Diet Pepsi."
