Jennifer Lopez 'Booty' Video Triggers Lube Deal

Jennifer Lopez looks so good in lube  in her new "Booty" music video with Iggy Azalea -- 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.
