The latest Twitter fracas is underway now ... the Beyhive is seriously voicing their displeasure over a video the "Milkshake" singer posted that shows her having her braids felt up by a couple ladies in Singapore, where Kelis is apparently visiting at the moment.

The clip shows Kelis seated at an outdoor table with a friend, who's filming, when these two gals start to caress and feel on her braids ... without notice or permission.

Kelis is taken aback but rolls with it, playing with their hair in return, and kinda letting them have their way -- they seem pretty fascinated with her 'do. While she looks confused, it doesn't seem Kelis is all that fired up about the awkward encounter ... more so amused.

That's where Beyoncé stans are jumping in ... chiding her for not showing the same amount of gusto for these women as she did for Bey's sample in "Energy" from her new album ... which used a part of Kelis's hit song, supposedly without being properly cleared.

You'll recall, Kelis was very public with her resentment over that. She called it disrespectful/ignorant ... and suggested Bey was somebody in the biz who had no soul or integrity. It was harsh, but it worked -- because Beyoncé yanked the sample and reworked the song in the end ... just one of many problems she had with the roll-out at the time.

Now, in light of this latest Kelis news ... some are saying Kelis is "all bark, no bite" -- among other mean comments -- suggesting this is objectively more objectionable, and that she picks and chooses when to get angry ... and may have a problem with Beyoncé, specifically.
