Pia Mia appreciates the kardashians

Pia Mia knows it pays to keep up with the Kardashians ... the 17-year-old singer/friend of Kendall and Kylie Jenner just signed a recording contract that will make her rich -- not Kardashian rich ... but close enough.
Pia signed a multi-album deal with Interscope which pays 1.3 mil for her first album ... and up to $9 million more if Interscope green lights her next three albums.
And according to the contract --  -- she stands to make even more in bonuses ... if the albums are hits.

Pia -- who was born in Guam -- got her start on YouTube and hit it big when Kim K. posted video of her singing a Drake song at Kylie's 16th birthday party -- with Drake and Kanye front and center.
