While many celebrities indulge in the guilty pleasure of McDonald's, it would appear that superstar designer Calvin Klein isn't one of them.
Klein's ex-boyfriend, Nick Gruber, revealed a hilarious anecdote about the time he convinced Klein to go for some classic American fast food.
"I made Calvin go to McDonald's and have a Big Mac, and he asked if they had it medium rare," Gruber told Page Six Magazine.
Klein didn't appear to enjoy the burger.
""He took a bite, and he was like, 'Ugh, what's this?' I'll never forget that story: medium rare for a Big Mac at McDonald's," Gruber said.
Gruber, an aspiring male model, is writing a tell-all memoir about his relationship with Klein, who is 48 years older than him.
