Gwen Stefani fans may think they know everything about the No Doubt frontwoman, but she still had a few secrets — until now. 

Stefani, 44, dished on her personal life before her debut on the upcoming premiere of season seven of The Voice. She participated in a special video segment, offering up some fun facts that fans and viewers likely didn't know about her.

"What everyone doesn't know about me is, I'm generally a lazy person," the singer spilled. "I really am. My favorite thing to do is sit in bed, eat pizza, and like, do nothing."

She also spoke about her first few jobs, explaining that at age 20 she was a makeup artist in a department store, and before that, her first job in her teens was at a Dairy Queen.

"When I started there, I fit in my outfit," Stefani said of the ice cream shop. "When I ended there, I did not fit in my outfit."

Watch the new The Voice judge open up in the video above, and tune in to the premiere on Monday, Sept. 22, at 8 p.m. on NBC.
