The college buds claim that they approached the Jersey Shore star a year ago and “asked her to become the celebrity spokesperson for a tanning product called Black Bronzer” — the name of her current tanning lotion — with the guys also taking credit for the design of the bottle.

No word yet from JWOWW’s lawyers.
