Celebrity Makeup Artist Busted for Stabbing Sister With An Umbrella

A big-time celeb makeup artist who's worked with Madonna, Miley Cyrus and Lady Gaga ... got arrested after cops say she stabbed her sister with an umbrella.

Law enforcement sources tell TMZ they were called to Sharon "Mama Makeup" Gault's home Monday in Santa Monica for a loud dispute. When they arrived, cops say Sharon and her sister had gotten into it, and Sharon's weapons of choice were a wooden clothes hanger and umbrella.

We're told Sharon connected with the hanger multiple times then picked up the umbrella and used it in a "stabbing motion." Her sister had minor scratches and bruises but refused medical treatment.

It's unclear what started the fight. Sharon was booked for assault with a deadly weapon.
