Vocal sensation Adam Lambert is set to hit the road as the frontman of iconic rock group Queen throughout north America later this year and he admitted that he can't believe how well tickets for the shows have been selling. 

The 'Trespassing' superstar is set to front the band again for another run of dates that will kick off on June 19 at the United Center in Chicago, and he took to his official Twitter page over the weekend to reveal his shock at the fact that the Madison Square Garden date in New York City has already sold out:

"We sold out Madison Square Garden!?! Woah!! @QueenWillRock."

Lambert returned to the social networking site in the early hours of this morning (March 17) and told his followers that he's irritated at how many people misspell Freddie Mercury's first name, adding: "It's FREDDIE people. Not FREDDY. Sorry... But.... Get it right!"

Meanwhile, he has recently been in the studio working on new material and teased that his new songs will surprise people: "Yes! My new music is gonna blow your minds!!! Killin the Studio!!!"
