Douglasville teen Alexandrea Lushington was the Queen of Poise Thursday when she was ousted in the semifinals of “American Idol.” Oddly, her friend and fellow contestant “Idol” David Archuleta was the one falling apart, tears flowing. Lushington ended up consoling him with a hug.

“I probably would have been the same way if he had left,” Lushington told me during a press conference Friday. “I’d never seen him that emotional before.” By coincidence, Lushington and Archuleta knew each other a few years ago when they competed against each other on CBS’s “Star Search.” (Archuleta outlasted her that time, too.)

They bonded as younger contestants: “We were minors so we were always in school. We ate lunch and breakfast with each other. Our dads would hang out together. We’d joke that our dads were like Laurel & Hardy.”

Lushington landed a song to sing Wednesday she had never heard before, the very mellow ’70s Chicago hit “If You Leave Me Now.” The judges were lukewarm, and the voters obviously weren’t impressed either.

“I could have done better and I’m capable of better,” she said. She took solace that judge Randy Jackson was a big supporter. “That gave me a slight piece of motivation. I don’t regret anything.”

TMZ a few days intimated that Robbie Carrico might be wearing (gasp!) extensions. This mtv.com story says it’s real. And so did Robbie today on the press conference:

“I’ve been growing this hair for a very long time,” he said. “I think it’s ridiculous they have to come up with something like that. No wigs!”

As for his Britney past, “I haven’t spoken to her in many years. It was a long time ago. We were friends on tour. That was pretty much the gist of it. It wasn’t that big of a deal. We went on a couple of dates. That was pretty much it.”

What song would have have sung next week if he had survived from the ’80s? Billy Idol’s “Rebel Yell.” Could he do the snarl?
