While usually Chrissy uses social media to take affectionate stabs at her husband, today she took it to the telly, onstage at the 2018 Emmy Awards.
She previously wrote on Twitter that her name has been mispronounced and she "doesn't correct people, ever".
"Gave up a long time ago", Chrissy said on Twitter.
The 32-year-old supermodel and TV personality dazzled on the red carpet in a silver Zuhair Murad gown.
A fan brought up the fact that Teigen says it wrong, too.
Then when Rancic asked if she preferred Tie-gen or Tee-gen, the mum-of-two made a shock admission. This seems like an obvious point, but it turns out we've been mispronouncing the author and singer's last names for years. It's all in good fun, of course (they quite clearly are sickeningly loved up), but it's just bloody amusing and I love it. Wrong order? I'll eat it. Taxi going to the wrong airport? She tweeted that people are saying her name wrong. "I'll change my flight". "I have to keep Grande [instead of Davidson] because my grandpa - I think of him with everything I do and he was so proud of my name".
I say "you", but it's truly just a deflection of blame.
