Alicia Silverstone Loved Harry Styles' 'Clueless' Grammys Look

And former 1D bandmate Liam Payne said he was proud of his "brother."

Harry Styles made a huge impression with his sultry performance at Sunday night's Grammy Awards and Alicia Silverstone definitely had some thoughts about it. The actress said that she was totally digging the ' "Clueless vibe" during the singer rocked on the red carpet before switching over to a black leather suit, green boa and nothing else for his show-opening "Watermelon Sugar" performance.

"I am loving the #Clueless vibes @Harry_Styles!!" Silverstone wrote alongside a side-by-side snaps of her character from the iconic 1995 coming-of-age comedy in which she's wearing a yellow plaid suit and pink boa, which was almost exactly the look Harry rocked on the red carpet, plus his now sold-out Gucci banana penis necklace. "Cher would be so honored (and totally approve!!) of this chic look. Congrats on your win at the #GRAMMYs last night!!! #WatermelonSugar," Silverstone continued.

And, just in case you missed it, Styles posted a behind-the-scenes snap of his stage outfit and posted it on Twitter on Monday (March 15) in which he posed with two bandmates with the simple caption, "Grammys, March 2021."

Harry also got some kind words from his former One Direction bandmate, Liam Payne, who gave Styles props on his win for pop solo performance for "Watermelon Sugar." "Congrats @hshq on your Grammy win," wrote Payne in an Instagram Story on Monday, according to fan screengrabs. "What a huge moment, proud to be your brother."

Additionally, Payne gave some love to the show's executive producer, Ben Winston, who revived the broadcast with a Jools Holland-style in-the-round performance space that created a warm, positive vibe during a three-plus-hour extravaganza that mixed live and pre-taped performances. "Side note congrats @mrbenwinston on a great show many more to come I'm sure," he wrote to the Late Late Show co-executive producer.
