"The Big Bang Theory" actress Kaley Cuoco proved that she can do no wrong as Ryan Sweeting's wife looked hot while debuting pink eyebrows to match her equally pink mane, and even while dressed in a slouchy outfit.

Three days ago, Kaley Cuoco shared on Instagram her new look, which she captioned, "@maneaddicts #bts #pinkbrows @jamiemakeupgreenberg photobomb @clsymonds."

One fan noted, "You totally pull it off, and how simply genius is this!? This makes sense and gorj."

"You are rockin' that pink!!!!! Too cute!" another said.

Another fan offered a hypothetical conversation on "The Big Bang Theory" if Sheldon sees Kaley Cuoco's pink eyebrow, as she wrote, "Sheldon: No, you have changed, everything is changing I can't take it I'm leaving... I like trains..."

But what if Ryan Sweeting's wife Kaley Cuoco's pink eyebrows started a trend?

Zimbio ran an amusing article where Kaley Cuoco's co-stars in "The Big Bang Theory" followed her pink eyebrows.

"Apparently, her foray into pink locks has sparked a full-fledged trend and inspired her Big Bang Theory cast to give the new look a try. Ha! Just kidding," Lani Conway wrote for Zimbio.

The article then posted Photoshopped images of Jim Parsons, Johnny Galecki, Simon Helberg, Kunal Nayyar, Melissa Rauch, Mayim Balik and Kevin Sussman, all with pink eyebrows.

"We're very much looking forward to an upcoming Big Bang Theory episode titled "The Pink Persuasion" - or something to that effect," she added.

Meanwhile, Kaley Cuoco ditched the pink eyebrows but Ryan Sweeting's wife still managed to look hot even when dressed in a "slouchy outfit."

Daily Mail published photos of "The Big Bang Theory" star wearing sweatpants and pink shirt on her way to yoga class in Los Angeles on Wednesday.

"The Big Bang Theory actress slicked her pink locks back into a low-maintenance hairdo, and let her skin breathe with not a trace of makeup," the article said. "She sported a pair of stylish glasses and looped on a grey sweatshirt around her neck."
