'Glee' co-star Chris Colfer will celebrate his 21st birthday working.

The Glee Live! Tour kicked off from the Mandalay Bay Hotel's stage in Las Vegas on Saturday and arrives at the Honda Center in Anaheim, California on Friday.

During an appearance on TBS' late night talk show Lopez Tonight, Colfer told his host comedian George Lopez that he didn't have any plans for his birthday.

“I didn't make any plans 'cause I knew I wouldn't remember any plans that I would make, anyway, the next morning. But its sad because I see 'bar' right there and I know I can't go in there for another, like, 2 days.”

Colfer added that he would be working on the tour show the night of his birthday and expected everyone in the audience to bring him alcohol.

Lopez then presented Colfer with a bottle of his favorite tequila, which included a note that read, “Do not open before May 27th.”

“On May 27th I will send it to you with flowers at your show and I want you to have your first tequila slushy, compliments of Lopez Tonight,” Lopez said. (The video is embedded in the right panel of this page.)
