JENNIFER LOPEZ 'BOOTY' VIDEO TRIGGERS LUBE DEAL

Jennifer Lopez looks so good in lube in her new "Booty" music video with Iggy Azalea and according to TMZ she now stands to make a bundle off a company that makes the stuff.

Reps for Doc Johnson Lube fired off the sticky to proposal to J.Lo after seeing the video last week -- and we're told they were especially inspired by the shots of her covered in a liquid they believe to be personal lubricant.

Bottom line -- Doc Johnson wants to be in the J.Lo butt business ... and the company is offering her a year's worth of its lubrication gel for free to prove it. The good doc also wants to discuss a long term sponsorship deal, if Jennifer's interested.

Something tells us this is NOT right up her alley -- but can't knock 'em for trying.
