Lori Loughlin and Zac Efron joined together for mutual friend Cade Hudson’s birthday in what became a Summerland reunion of sorts. For those unfamiliar with Summerland, it was a short-lived WB series that first premiered in 2004.

Despite its short run in the U.S., Lori Loughlin, Zac Efron, and their co-stars have a huge current fan following in countries around the world where Summerland went into syndication.

Even though Summerland had a short life span here in the U.S., it’s plain to see Lori Loughlin and Zac Efron’s careers did not. Fans can check out Zac Efron in his upcoming film Dirty Grandpa. It premieres on January 21.

Lori Loughlin, as her fans surely know, is set to reprise her role as Aunt Becky in the Netflix reboot of Full House. Called Fuller House, the series premieres next month.
