Avril Lavigne is already 36 but her recent Instagram post seems to belie this.
In it, the singer-songwriter looks ageless in a bright green two-piece bikini.
"Summer in Malibu,” she wrote as caption.
Fans were stunned.
Some of them apparently noticed that one of the photos allowed a bit of a nip slip.
In fact, it even caused huge debate.
Said one, "Obviously too busy 'sneaking' her nipples into micro bikini photos. Apparently that's art...... Disgusting..."
"If you have such an issue with the fact that she has nipples (which shockingly all people have) then perhaps you should consider chopping your own off if they're that offensive," retorted another.
Some are wondering when she will come out with new music.
"You promised us a new album not this," said a fan.
Added another, "I'd rather you head to a studio..."
