Adam Lambert At 2011 American Music Awards [PHOTOS]

It’s been two years since Adam Lambert caused a firestorm of controversy with an over-the-top sexy performance of his debut single For Your Entertainment at the 2009 AMAs.

The performance, which featured simulated sexual acts and a guy-on-guy smooch, resulted in ABC receiving several complaints, which led to ABC canceling a few of Adam’s promotional appearances on other shows on the network.

That is apparently now all water under the bridge at ABC, because last night (November 20) Adam Lambert hit the red carpet with his boyfriend, Sauli Koskinen, at the 2011 American Music Awards held at Nokia Theatre L.A. LIVE on Sunday (November 20) in Los Angeles.

He was also a presenter last night, who introduced One Republic. On stage, an appreciative Lambert said, “Wow, has it been two years already!? Thank you guys very much.”

We imagine he’ll be back next year performing one of his hits from his forthcoming album Trespassing.

Watch his return…
