Michelle Obama, overcome with emotion, makes the announcement.

Michelle Obama is paying tribute to Stephen “tWitch” Boss.

The former first lady, 58, paid tribute to the dancer after learning of his suicide on Wednesday at the age of 40.

They originally met through her regular appearances on The Ellen Show, where he worked as a DJ and co-executive producer, and through his participation in the Let’s Move! initiative she launched in 2010 to combat childhood obesity.

She expressed her sadness at his death and described him as a “wonderful energy,” characterizing him as “someone who emitted compassion and positivity and made sure that people around him could feel it.”
