So much for Zayn Malik's statement that the boys of One Direction would remain "friends for life."
On Wednesday, the 22-year-old singer threw some serious shade at Louis Tomlinson on Twitter, writing, "Remember when you had a life and stopped making bitchy comments about mine?"

Zayn received some backlash for his message and later tweeted: "Don't know why I'm being attacked for defending myself, people got it twisted! I love my fans?! Every single one of you."
The drama is all in response to Louis' most recent dig at producer Naughty Boy, who posted a pic of he and Zayn.
"Replace this," the producer wrote, which not surprisingly, One Directions fans weren't too happy about.
"@NaughtyBoyMusic Jesus forgot you were such an in demand producer .... How does it feel to be riding on the back of someone else's career?" Louis commented.
He also took a not-so-subtle dig at the heavily filtered photo.
"Remember when you were 12 and you used to think those Mac filters for your pictures were cool haha! Some people still do HA!," he also tweeted.
Naughty Boy and Louis have traded blows in the past. In March, he criticized the producer for posting an old demo for the boy band's last album, which fans quickly presumed was a new solo track from Zayn. Fans then began to question Zayn's motives for leaving the successful British boy band, as he said, to "be a normal 22-year-old who is able to relax and have some private time out of the spotlight."
"Wow @NaughtyBoyMusic you're so inconsiderate pal, seriously how f**king old are you ? Grow up! #masterofallwisdom," Louis fired back at the time.
One person now also commenting on Zayn's desire to be "a normal 22-year-old?" Oasis' Noel Gallagher, who has less than kinds words for him.
"The greatest quote was -- I laughed out loud when I read it -- 'I just want to be a normal 22-year-old,'" he tells Rolling Stone in a new interview. "Pfft. Who wants to be a normal 22-year-old?! Hang on a minute. You can be fu**ing anything that moves and gettin' paid half a million dollars a week, you fu**in' idiot."
"I'll say this to you, Zayn: You might have wanted to be a normal 22-year-old, but you won't want to be a normal 25-year-old," he laughs. "For Zayn, though, I'd say, 'Fu**in' get a good accountant because life is very f**kin' long.'"
