Selena Gomez may end up paying thêm than a million bucks as part of a settlement with a perfume company that sued her for bailing on an endorsement ... we have learned.

Adrenalina, Inc. sued Selena, claiming it poured $2 mil into R & D for a perfume line she was supposed to front. The company claimed Selena bailed and violated the deal. Selena counter-sued, claiming she backed out because the company was going broke and couldn't afford to produce the product.

We just obtained settlement docs which hiển thị the case has been dismissed. But sources familiar with the situation tell us ... Selena will cough up a six-figure sum to end the lawsuit.

We're also told there's another component to the settlement, which could bump the cost up to the 7 figures.

Neither side would bình luận on the settlement.
