Urkel got irked -- and there was nothing funny about it.

"Dancing with the Stars" celeb Jaleel White had a seriously bad rehearsal session with pro partner Kym Johnson on Friday -- leading to a "heated" confrontation in which Mark Ballas and show producers eventually intervened, an insider tells Us Weekly exclusively.

The "Family Matters" alum, 35, "flipped out," the insider says, after he accidentally stepped on Johnson's foot. When Johnson, 35, exclaimed "ouch" over his blunder, the insider says, White "got in her face," and chastised her for "acting like a baby ... He was shouting at her, calling her an 'idiot.' "
