Ryan Seacrest, the perpetually upbeat host of "American Idol" on Fox, is joining the board of trustees of the Los Angeles County Museum of Art.
Leaders at the museum announced on Monday that Seacrest is among four new board members, bringing the board's total to 54.
The other new trustees are Ann Ziff, the philanthropist who serves as chairman of the Metropolitan Opera in New York; Nicole Avant, wife of Netflix executive Ted Sarandos; and Anne Emerich Palmer, wife of L.A. real-estate developer Geoffrey Palmer.
Seacrest is the latest entertainment name to join LACMA's board, which continues to be co-chaired by Terry Semel, the former Warner Bros. and Yahoo executive, and TV producer-writer Andrew Gordon.
Other prominent Hollywood names on the board include Brad Grey, the chairman and CEO of Paramount; Bryan Lourd of Creative Artists Agency; and Oscar-winning producer Brian Grazer.
Seacrest is a collector of postwar and contemporary works, according to the museum. The TV and radio personality, who has been hosting "American Idol" since 2002, has made numerous charitable contributions to various causes through his personal foundation.
Ziff is the widow of William Bernard Ziff Jr., the heir of the media company Ziff Davis. In 2010 she gave $30 million to the Metropolitan Opera, the largest single gift from an individual in the opera's history.
