Liv Tyler’s mother, rock legend Bebe Buell, has slammed the most famous mom-ager in the world -- Dina Lohan -- saying that she needs to start being a mother to her troubled daughter Lindsay.

Bebe had some harsh words for the Lohan matriarch in an new interview with Steppin’ Out magazine.

“What her mother has done with Lindsay is morally wrong and disgusting. She should back off. Lindsay is the one with the talent. She's the star,” Bebe told Chaunce Hayden.

“Dina Lohan's relationship with her daughter Lindsay disturbs me,” Liv’s mom said.
