Rob Lowe has reached a new low.
In a recent interview with The Telegraph, the Parks and Recreation star was asked whether he is "more or less vain than British men".
"That's a low bar! Can we talk about William? " the actor responded.
"I mean, the future king of your country let himself lose his own hair, so when I say British men set a very low bar ..." he continued. "Honestly, one of the great traumatic experiences of my life was watching Prince William lose his hair. He's going to be the f–king king of England!"
"There's a pill [to combat hair loss]...The first glimmer that a single hair of mine was going to fall out, I was having stuff mainlined into my f–king veins. And that's what I did for the next 30 years," he added.
After the actor's quotes went viral, Twitter slammed Lowe for his mockery of the royal's hair.
"Perhaps the future king has more important issues to focus on. Not shallow Hollywood vanity," one Twitter user wrote.
In September 2017, the Duke of Cambridge joked about his hairline to a hairstylist saying,"I don't have much hair; I can't give you much business." This past March, HELLO! put out a story that Kate Middleton jokes about Prince William's hair all the time.
While maybe Lowe went a little overboard, we have a feeling the prince will have no hard feelings.
