The tiny cross, inked on her middle finger, looks like the one Bieber got underneath his eyes earlier this year, reported Acehsowbiz.
Richie, 18, documented the experience on Snapchat Thursday, September 8.
She also let her Instagram followers see the tattoo in a picture she posted on the social media along with a shout-out to Jon Boy. "Wanted this cross forever!! Thank you @jonboytattoo you're the best," she wrote in the caption.
The other tattoo Richie got that day was a "13:4" on the back of her neck.

That's likely a reference to the beloved bible verse that reads, "Love is patient, love is kind. It does not envy, it does not boast, it is not proud."
Bieber apparently also inspired the tattoo as he has an entire verse of the Bible on his shoulder.
Richie debuted her tattoos shortly after she opened up about her special equation with Bieber.
"We have a special relationship. Justin is very easy to talk to, and that's hard to find with people in Los Angeles," the daughter of singer Lionel Richie said.
