Michael Bublé has become a singing sensation around the world and is ready to once again sing Christmas songs in NBC's annual holiday special "Michael Bublé’s Christmas In Hollywood." However, his first experience with Hollywood was not a good one, as he got caught taking food that belonged to Scully (Gillian Anderson) and Mulder (David Duchovny) on Fox's "The X-Files."

In an interview with TVLine, Bublé revealed that he'll never forget a Hollywood lesson he learned over 10 years ago while an extra on "The X-Files" Season 3 -- which is to never take hot dogs that belong to the stars. After doing this, the young singer was fired on the spot.

"I swear to god, I was starving and I grabbed a hot dog off the craft services table," he told TVLine. "And this woman said I would never work again in Hollywood. I would be blacklisted and I would never, ever work in the business!"

This isn't the first time Bublé has been fired from a job. Bublé told TMZ in January 2013 that the worst job he ever had was at a Chucky E. Cheese, where he was fired for being too skinny to dress up in the rat costume.

While he hasn't been fired from singing on NBC each holiday season, the 40-year-old singer also told TVLine this may be his last year doing the annual special. He's expecting a second child and there is a lot of work that goes into each special, as well as his tours, so he feels it might be time to step away from the show. Bublé started doing the annual concert in 2011.

For the possible last, "Michael Bublé’s Christmas In Hollywood," the singer will be joined by Celine Dion, Tori Kelly, and Sharon Jones & the Dap-Kings. Bublé will perform songs like "This Christmas," "Here Comes Santa Claus," "Jingle Bells," and "White Christmas." The singer-songwriter is also expected to debut a new song called "The More You Give (The More You’ll Have)."

While Bublé has been busy, Fox's "The X-Files" is set return to TV in January 2016 after going off the air in May 2002. The show will air as a six episode mini series continuing Scully and Mulder's story as they search for the truth.

Michael Bublé’s hour-long holiday special, "Michael Bublé’s Christmas in Hollywood," will air Thursday, Dec. 10, at 8 p.m. EST on NBC.
