Gwen Stefani rocks super short dress during 'Tonight Show' appearance

Well that could've been bad ...

Gwen Stefani appeared on "The Tonight Show" on Wednesday -- and she barely avoided a wardrobe mishap with her super short dress! The 47-year-old singer wore an eye-catching Kaufman Franco mini dress (emphasis on mini) with some shoes to match.

The "Voice" coach's daring frock looks almost too short when she walked onto the stage, but the ensemble definitely flattered her super toned legs. She wore her platinum blonde tresses in a slick-straight style while wearing heavy eye makeup.

Photos of Stefani sitting down while talking to host Jimmy Fallon proves just how skimpy the outfit is! She gave cameras a subtle view of her booty will sitting down crosslegged.

Of course, the No Doubt frontwoman gushed about boyfriend Blake Shelton during her interview with Fallon. The adorable pair has experienced bumps along the way, just like any couple. Gwen hilariously admitted she was nervous to take her country crooner beau to Disneyland for the first time!

"He won't do the rollercoasters," she revealed. "That was literally, like, that was almost a deal breaker for me. I was like, 'I don't know.'"

And when it came to their Valentine's Day plans, they unfortunately spent the holiday of love away from each other. She went on "Today" earlier this week, where she revealed that he showered her with flowers and lots of texts.

The blonde beauty is currently promoting the upcoming season of the "Voice," which is now on season 12. This will be the first time she and Shelton will appear on the show as a couple.

The hit show returns on February 27 on NBC.
