Kaley Cuoco and Amy Davidson have 8 Simple Rules reunion with John Ritter's wife Amy Yasbeck

The Hennessy family came together again — and for a great cause.

The cast of 8 Simple Rules reunited Thursday in honor of their late onscreen patriarch John Ritter at the John Ritter Foundation's From the Heart event in Los Angeles.

Kaley Cuoco and Amy Davidson — who starred as the loving yet antagonistic sisters Bridget and Kerry — posed for photos alongside Ritter's wife, Amy Yasbeck, on the red carpet. Katey Sagal and Martin Spanjers, who played mom Cate and son Rory, respectively, were also in attendance at the event.

The ABC sitcom, which premiered in 2002, starred Ritter as Paul, an extremely protective parent who is very concerned about whom his daughters are dating. Ritter died suddenly from aortic dissection in 2003 while filming season 2 of the show. After a hiatus, it returned for an additional two seasons before ending in 2005.

"Amy Davidson, Martin Spanjers, and Katey Sagal… just, thank you," she continued. "This is really awesome. I think John is laughing his ass off right now. He cannot believe we're here."
