Terry Richardson is used to having still-teenaged women take off much of their clothing and pose up for him in a provocative manner.
Now it seems that Pia Mia is no different.
Indeed, she is firmly following in the footsteps of her BFF Kylie Jenner, who marked her 18th birthday with her own eyebrow-raising Richardson shoot, as seen in Galore magazine earlier this month.
Miley Cyrus, 22, did something similar two years ago: the resulting snaps caused oodles of controversy at the time, which presumably is what everyone involved wanted.
By comparison, 19-year-old Pia Mia's just-seen snaps are relatively tame, although they still boost plenty of Terry trademarks – pouting lips; open mouths, and sprawled legs.
Very much a rising star, Ms Mia scored her first hit earlier this year with Do It Again, which featured Tyga and Chris Brown. The accompanying video has also now notched up 75million views on YouTube.
