Barbara Corcoran is competing on Season 25 of ABC's Dancing with the Stars this fall.

Barbara is a 68-year-old businesswoman, investor, speaker, author and TV personality, who is best known for starring on ABC's Shark Tank.

Barbara is partnered with Keo Motsepe for the Dancing with the Stars season, and she brings a lot of personality and laughs to the ballroom.

But when she made her Dancing with the Stars debut last week, Barbara and Keo unfortunately landed in thirteenth -- and last -- place on the judges' leaderboard after earning only 14 points for their salsa routine.

Barbara may be in jeopardy of elimination soon based on her judges' scores, but we'll see if her fans come through and vote for her to stay.
