Rocker Adam Lambert reveals the secret to his success on Monday's E! True Hollywood Story.

The one-hour special will take a look at the America Idol season 8 runner-up's meteoric rise to fame, his decision to publicly come out gay, and the secret to his success.

“I'm very fortunate to have parents that recognized that I was different and recognized how I was special,” Lambert says on the program. “They didn't ever try to box me it.”

In a tweet from Europe, where Lambert is currently performing his Glam Nation tour, the Whataya Want From Me singer reminded his fans to tune in: “E! THS time! Hope you like. :)”

The special will also cover the 28-year-old rock star's decision to share his personal life with his fans.

“My fans have been really supportive of my choice to be open and upfront about my sexuality and my lifestyle,” Lambert says. “I have come from the belief that hiding something from people and manipulating what they think of you is far more offensive and disrespectful than just being upfront and being who you are.”
