Keri Hilson's Alluring Popsicle Vid Won't Stop Her From Keeping it 100

Keri Hilson forgets the world's watching her social media ... at least that's her explanation for flaunting her, umm ... popsicle eating skills.

We caught up with Keri Tuesday at LAX and eased into the convo -- about the hypnotizing Snapchat vid she posted in June. Her fans, and others, were buzzing about it, but Keri never discussed what the hell she was doing. After all, she was in the middle of shopping when it went down ... so to speak.

Well, here's the full story. Hint: booze was involved. Also, she admits it could happen again ... not that anyone's complaining.
