Maya Hawke is dishing some family secrets.

The "Stranger Things" actress, 24, opened up about lying to her famous father, Ethan Hawke, on "Watch What Happens Live With Andy Cohen."

Maya recalled being in the worst trouble she's ever been in when she lied to her dad.

"I lied. I said I was going to therapy and I really went to lose my virginity," Maya told Cohen and guest Bryan Cranston on Tuesday's episode. "I can't believe I just said that. My father was very upset."

Maya recalled Ethan giving her a "very hard time" about her whereabouts the evening she lied.

"He went, 'Where were you? Where did you go?'" Maya recalled. "And I said, 'How am I supposed to have secrets if I can't tell lies?'"

Cohen was impressed by Maya and said, "I would think, knowing your father, that he actually respected that." 

Maya confirmed Cohen's assumption saying, "He did! He was like, 'F--k this kid!' He was like, 'Oh, that's good.'"
