"Twilight" star Nikki Reed should probably invest in some mace ... 'cause it might've helped her escape the creepy clutches of the Go Daddy nerd ... who GRABBED AND PULLED HER outside an L.A. club last night in an effort to deliver a very unwanted kiss.
Reed was leaving Bootsy Bellows with her husband Paul McDonald ... when Jesse Heiman -- the guy who famously kissed Bar Refaeli in the Super Bowl ad -- darted out of the club and beelined to Nikki for a goodbye smooch.
Nikki politely tried to resist and break away ... but Heiman grabbed her arm with one hand ... and forcefully pulled her closer to him with the other ... while lunging over to press his lips against her face.
Nikki resisted ... and even vocalized her displeasure to the 35-year-old pitchman -- "You're holding me ... my husband's RIGHT THERE."
Heiman REFUSED to be denied and landed the kiss anyway ... right before Nikki managed to escape his grasp and scurry away.
Ya gotta watch the clip -- it's about as awkward as it gets.
