Is it true that Jayne Mansfield had a genius level IQ?

she supposedly had an IQ of 163, but those weren't the numbers most men were interested in.

Mansfield won several beauty contests while living in Texas, including Miss Photoflash, Miss Magnesium Lamp, and Miss Fire Prevention. The one title she turned down was Miss Roquefort Cheese, because it "just didn't sound right." Frequent references have been made to her very high intelligence quotient. Mansfield advertised her I.Q. as 163, spoke five languages, and was a classically trained pianist and violinist, but such intellectual abilities were inconsequential to her career. Mansfield admitted her public didn't care about her brains. "They're more interested in 40-21-35," she said.
