Actress Gabourey Sidibe isn't the only talented one in her fam -- and last night her mother proved it when she totally killed it with her audition for "America's Got Talent".
Alice Tan Ridley, Gabby's mom, has spent years performing in subway stations for money -- and last night, she sang a rendition of Etta James' "At Last" that blew away both the audience and the shows' judges.
No surprise here -- she made it to the next round.
