Entertainment Tonight” is launching its first-ever magazine, in conjunction with the start of the show’s 35th season, which premiered on Sept. 14.

The series of special edition collectible magazines will launch with “ET: Before They Were Famous,” which hit newsstands Sept. 15.

Each issue, distributed by Topix Media Lab, will be a single topic, 100-page, glossy magazine that will include celebrity photos, stories and commentary. All will be sold at more than 50,000 newsstands nationwide and online.

“I am thrilled that after 35 years of leading the way in entertainment news, ET has pulled from our vast archives to create our first glossy magazine revealing a side of celebrity rarely seen,” said “ET” exec producer Brad Bessey.

The first of the collector’s edition magazines, “ET: Before They Were Famous” will look into the early lives of some of the biggest and most popular celebrities and chronicle their journey from virtual obscurity to super-stardom. The issue will feature before-and-after star stories, childhood photos, embarrassing first jobs, young romances and more. Some examples include Jennifer Garner’s transition from high school nerd to bombshell movie star or Hugh Jackman’s journey working as a children’s party clown to becoming Wolverine.

“Entertainment Tonight” is hosted by Nancy O’Dell and Kevin Frazier, and exec produced by Brad Bessey. Nischelle Turner and Cameron Mathison are correspondents.
