We wonder if he was thinking about Kate Hudson!
Although he wasn't on the promotional poster, Nick Jonas still made his way onto the stage of the Tidal X 10/20 concert in Brooklyn, NY!
Performing in front of a VERY excited crowd, the crooner completely sang his heart out, and looked EXTREMELY sexy in the process!
We absolutely ADORE seeing the 23-year-old do his thang!
To see the Ah-mazing performance, ch-ch-check it out (above)!
