Ariel Winter's brother is standing by his mother's side.

On Wednesday, TMZ reported that Modern Family actress Winter, 14, had been placed under her older sister Shanelle Gray's guardianship after allegations of physical and emotional abuse emerged against her mother, Chrisoula "Crystal" Workman.

Us Weekly spoke with Winter's brother, Jimmy Workman, about the allegations against their mother, and he tells Us they are not true.

"There is no truth to these allegations," he said. "The allegations made 20 years ago are not true and the ones today are not true."

According to TMZ's report, Gray was also removed from Workman's home as a young child based on similar abuse claims.

"This is a mother who does everything for her kids," Jimmy told Us. He added about their mother, "Chris misses Ariel and wants her to come home."

Winter, who got her first acting job at the age of 6, plays brainy middle child Alex Dunphy on ABC's hit Emmy-winning  sitcom.
