Adam Lambert will return to the American Idol stage this season.
A few hours after Allison Iraheta and Kris Allen performed for fans, Lambert Tweeted today:
"Yes, I have been booked on Idol! Can't reveal the date yet but it's a ways off... So excited. Kris and Allison were awesome last night."
They sure were. But Lambert's debut album sold the most copies of any season eight finalist and his appearance later this year is sure to draw huge ratings.
