AceShowbiz - Billie Eilish showed support for fellow musician Charlie Puth. The "Happier Than Ever" hitmaker called out Benny Blanco after he called Charlie a "f**king loser" in his TikTok video.

On January 7, Billie shared a video of her reacting to Benny's post in which he taunted the "We Don't Talk Anymore" crooner for making TikTok videos all day. "What do you do all day, Benny? The same thing. Literally, the same thing," Billie said.

Charlie caught wind of Billie's post and quickly thanked her for defending him. "Thank you," the "Attention" singer wrote in the comment section.

Benny has been posting videos making fun of Charlie's voice for months now, telling him to "shut the f**k up Charlie." After remaining mum for a while, Charlie decided to speak out against Benny, who is also known as Benjamin Levin.

"You know, man, these videos were really funny at first," Charlie said back in November. "I don't exactly know why you've been so mean to me these past couple of months, but it does genuinely hurt my feelings. I used to look up to you, and I don't know where all this is coming from."

Despite being called out, Benny didn't stop. The 33-year-old songwriter and producer further dissed Charlie. "I know why I made this video because you're a f**kin' loser, Puth," he responded to Charlie. "Look at you: You sit in a room all day and make TikToks…Dude, what the hell's wrong with you? Look at your hair. It looks like you've got a toupee or a wig on or something. Get a grip and get a f**king haircut."

People blasted Benny for his constant diss at Charlie. "From what I can see Benny's got a lil elementary school crush on Charlie…," one person commented. "It's got to the point I genuinely don't know if this is real and I low-key feel bad for Charlie," another user added, but Benny insisted that Charlie "brought it upon himself."
