Leave it to Kristen Stewart to have the most awkward wardrobe malfunction EVER.
The quirky actress suffered a serious nip slip last night at the Hollywood Film Awards when her strapless dress slipped down and exposed her nipples -- all while she was presenting an award on stage in front of a live audience ... which included her ex-boyfriend, Robert Pattinson.
Trying to show Rob what he's missing?
Despite their rocky history, Kristen was hoping she'd run into her former flame at the event.
"She’s not sure how [Rob] feels about seeing her, but she hopes their paths will cross and they can spend some time together," a source told Hollywood Life. "It’s been so long and if not tonight, she doesn't know when they would see each other again.’
Rob, who showed off an unusual new haircut at the event, avoided the awkward run-in by skipping out on the red carpet.
