Up-and-coming actress Lexi Underwood is trying to clear up a persistent rumor that she’s the daughter of famed “L.A. Law” star Blair Underwood.

“I have seen [the rumor] on blogs, in different articles and even on my biography that Blair Underwood is … my dad,” Lexi, a star of Hulu’s “Little Fires Everywhere,” told Page Six.

“We’ve been trying to change that,” adding, for the record, her father is Alex Underwood.

“My parents are reading articles and they’re like, ‘What?!’ I don’t even look like [Blair]. The only thing we have in common is that we share the last name and we both are black … He is a great actor but I’ve never even met him.”
