But now Kylie Jenner has signalled she could be ready to say goodbye to her plumped-up lips.
Speaking in a new video on her app with make-up artist Joyce Bonelli, Kylie mentions she has been favouring a more natural pout of late.
"You know what’s weird? I’ve been into small lips lately," Kylie says in the clip.
"Like, I want them to look small."
And while we can't see Kylie reverting to her teenage thin-lipped look any time soon, it's true she was rocking a more natural-coloured pout last night, at least.
The 19-year-old was pictured at New York's Soho Hotel for the Balmain X H&M show, which featured her big sister Kendall.
Clad in a show-stopping embellished Balmain dress, Kylie could afford to tone down her lips a little for the night.
And with her black bob making a return too after a series of blonde (and green) wigs, it seems like the reality star is ready to embrace her true self again… at least for a while.
