Showbiz PR vet Scott Seomin has been tapped to succeed Chastity Bono as the entertainment media director for the Gay & Lesbian Alliance Against Defamation.

Seomin was recruited to further heighten the advocacy group’s profile and “energetically lead our efforts in the entertainment media industry,” said GLAAD exec director Joan Garry. Bono departed in June after 18 months in the post.

Seomin joins GLAAD after spending the past two years as PR chief for John Tesh and Tesh’s GTSP Records. From 1990-96, Seomin headed media relations for Paramount’s “Entertainment Tonight,” as well as juggling PR responsibilities for GTSP. Earlier in his career, he served stints as a PR exec for the E! Entertainment Television cabler and Warner Bros.’ syndie arm.

Seomin also is a regular contributor to prominent gay- and lesbian-themed publications, including the San Francisco Bay Times, the L.A.-based Edge, the Chi-based Windy City Times and the Philadelphia Gay News.

“GLAAD’s work resonates with me on many levels,” said Seomin. “My hope is to have the entertainment industry utilize GLAAD in a more formalized way and to give GLAAD an even stronger voice in newsrooms across the country.”

Founded in 1985, GLAAD aims to promote “fair, accurate and inclusive representations of individuals and events in all media as a means of combating homophobia” and discrimination against gays and lesbians.
