"In the first film we had a very limited budget, and we would entertain extras in the strip club between takes," he told MTV News. "Basically Channing would just shove a microphone in your face, like, 'Do something!'"
When it was time to do the sequel, Tatum remembered that Bomer once sang for the extras, and made sure that his co-star recreated the magic not once but TWICE in "Magic Mike XXL" -- and both times, he had to perform live.
"It was an incredible gift that Channing gave me, and also really terrifying!" Bomer said.
"Magic Mike XXL" hits theaters July 1.
