If you like someone and it is their birthday, it's sufficient to send them a card or buy them a pint. But why do that when you could get their face tattooed on your face?
Earlier in the month, New Zealand native Karter shared a tweet that read: "Finally know what I'm getting Harry for his birthday...."
However, few would have guessed it would be the 'gift' she revealed on Instagram yesterday.
The 24-year-old shared pictures of her new face face on Instagram, with the caption: "Mama, look what I made me do."

What do you reckon gang? Best birthday present ever or what?
The ink art was administered by famous LA tattoo artist, Romeo Lacoste, and even he seemed a little shocked by her choice of gift. Writing on Instagram, he said: "I can't believe Kelsy Karter got Harry Styles tattooed on her face."

Karter's love for Styles is well-known - if indeed you had heard of her prior to this bold tat.
Speaking to i-D in July, the 24-year-old said: "What I love about him from a professional standpoint is that he was the poppiest of pop stars, and then he went off on his own and made a classic rock album.
"For someone like me who wants to live in that world who hasn't been in a boy band, he has opened the door for me. He's introduced the kids to the kind of music I want to make. For that, I'm really grateful.
"I also just want his career. I feel like I'm a female version. I actually moved to America to act, and music became my main thing. Rock 'n' roll is my passion.
"I really want to work with him. Let's work, Harry. Where you at? Mark my words: I'm getting a song on his album."
She failed to add though that she was also getting a tattoo of his face on her face.
Though, while she may have endless professional admiration for Styles, it is also clear that she fancies the pants off him.
So in case the old face tattoo wasn't proof enough, there's that too.
Whether or not Karter has ever even met Styles is unclear, though she's clearly doing everything she can to make sure he knows about her. Some would say this latest move may have been a step too far, but hey, if she ends up with a song on his album and it's actually just a transfer, then she'll have the last laugh.
That said, if she doesn't get acknowledged by Styles but ends up with that tattoo forever, then she will not.
Either way, it's a sign of the times, ey?
