Adam Lambert has come a long way since "American Idol" and is taking a reflective look back with his new single, "Better Than I Know Myself." The pop star, who turns 30 on Sunday, tells MTV News that the first release from his forthcoming sophomore album, Trespassing, is "about the relationship you have with yourself, between your dark and light side. It's about duality; it's about that balance and finding it and struggling to maintain it and what it means."

It's been a tumultuous few weeks for the singer, who was arrested in Finland in late December after a verbal argument with his boyfriend, Sauli Koskinen, outside of a Helsinki bar turned physical. Lambert later admitted to Ellen DeGeneres during an appearance on her show last week that alcohol was the main catalyst for the altercation, telling the host, "When you add alcohol to a situation, things can get out of control. ... What happened was, we had too much to drink. We screwed up. There was no injuries, no violence. It was more just childish, foolish messiness." With the March 20 release of Trespassing nearing, Lambert's focus has returned to his music and his new single. "It's so universal," Lambert tells MTV News. "It's ... in the middle of a bunch of different genres, and I think that no matter who you are, if you've been in a relationship, you know what that is." Lambert collaborated on the track with Dr. Luke (Britney Spears, Katy Perry) and songwriter Claude Kelly, who co-wrote his debut single, "For Your Entertainment." He admitted "Better" has a lot in common with his Pink-written top 10 smash "Whataya Want From Me," saying, "There is something similar to "Whataya Want From Me," and I think that's the reason I'm really glad it's the first single." He also revealed that the upcoming video for the track is "like a cousin" to the "Whataya Want" clip. Lambert said the song deals with the insecurities that come with being in a relationship. "[It's about] that moment where you're like, 'I need you, I love you,' where you have to reassure your partner," adding, "No matter what kind of relationship, everybody can relate to that moment."
