Stylist-turned-chef Gok Wan, 43, was on This Morning to whip up a tasty and quick noodle recipe.
But Gok may have unintentionally taken a swipe at Holly by branding her “simple”.
“This is actually for you, I’m going to call this dish ‘Holly Willoughby’s Noodles’,” he explained.
“Did Gok just call Holly super simple?”

“It’s broth, it’s super simple, it’s virtuous and it’s very healthy. You can prep, cook and eat in 15 minutes.”
“It smells so good as well!” Holly said, as she and Phil laughed at the quip.
However, This Morning viewers soon brought Gok’s catty remark to everyone’s attention.
“Did Gok just call Holly super simple?” one viewer asked.
“Super simple…just like Holly,” another tweeted.
And a third laughed: Gok just called @hollywills ‘super simple’ on This Morning…”
