For his part, Lambert said all the time together only solidified his initial impression of Allen. "He's further proved my opinion that he is one of the nicest, most laid-back and gracious guys I have ever met," he said. "He has a great sense of humor and nothing fazes him. It's refreshing to be friends with someone so comfortable in his own skin."
In one way, it shows what Lambert has realized about having a career as an entertainer.
"In order to make a living in show biz, you have to be good with people and be a team player."
He is upbeat about working alongside Allen and has become one of his ex-rival's biggest fans. "I am so excited for his future success," he said.
Lambert's also looking forward to his own success, as he works on releasing his solo album in November, which is expected to have some sexy songs. But he has more far-reaching plans as well. "In five years, I see myself making more records and music videos and hopefully crossing over into other forms of entertainment media," he said.
Acting is one possibility. "I would love to try film and TV. Movie musicals are back," he said excitedly. He holds out hope for one part in particular. "Dream role would be Judas in an edgy version of 'Jesus Christ Superstar,' " he said.

"One: Never stop working until you want to stop working. Two: Hold on. It's about to get crazy. Both are extremely appropriate," Cook said.
