Laurence Fishburne‘s 19-year-old daughter is making a serious push to break into Hollywood — and she’s doing it with a hardcore sex tape.

TMZ has learned Montana Fishburne is starring in a porno flick for Vivid Entertainment – explaining, “I’ve watched how successful Kim Kardashian became and I think a lot of it was due to the release of her sex tape.”

Unlike the celeb she admires — Montana is not arguing that her tape was stolen or obtained illegally.

We’re told the flick is set to be released in August.
