The former Microsoft CEO was spotted breaking it down with some impressive sideline dance moves as the Black Eyed Peas singer performed at the Staples Center Wednesday evening during his team's game against the Los Angeles Lakers.
He screamed, he flailed his arms, and he danced as if no one was watching.
Ballmer made headlines when he purchased the Clippers last August for $2billion in the wake of the Donald Sterling scandal.
And while the sale was one of the most expensive in NBA history, it has so far paid off for Ballmer, with the Clippers currently in second place in their division.
The team also improved their record last night, as after Ballmer's energetic dance performance they went on to defeat the Lakers.
