The actress also revealed that McConaughey has a strong odor, saying she could “smell him from a mile away.” [away].

The Interstellar star previously addressed his deodorant stance in a 2008 interview with Playboy, saying that Hudson hinted that he needed to do something about his body odor.

“She always carries a salt rock, which is a natural deodorant, and says, ‘Would you please put this on?'” he said. “I’ve never worn it. No cologne, no deodorant.”

McConaughey added, “The women in my life, including my mother, have all said, ‘Hey, your natural scent smells, first of all, like a man and, second of all, like you.'”

Despite using anti-deodorant, Matthew insisted he took his personal hygiene seriously, claiming he showered multiple times a day and brushed his teeth up to five times a day.

He just doesn’t like smelling like anyone or anything else.

The Oscar winner first expressed his distaste for deodorant in his 2005 Sexiest Man Alive profile, telling People he hadn’t used it “in 20 years.”
