Bianca Lawson says her "Westworld" audition was a fiasco because her bra -- that was filled with oil -- exploded as she angled to get the role.
Bianca was at LAX Friday night when she told our photog about her wonky bra. Sadly, she didn't get the part on the HBO monster hit.
Lawson, whose credits include "Pretty Little Liars," "Buffy the Vampire Slayer" and "Teen Wolf" ... has high praise for Tina Knowles. As you know, Tina's hubby, Richard Lawson, Is Bianca's papa.
