Kelly Rowland -- Beyonce's New Haircut Ain't THAT Shocking

Beyonce Carter crushed it when she decided to chop off all of her hair -- 'cause when it comes to style, B can do NO WRONG ... so says her Destiny's Child bandmate Kelly Rowland.

"Beyonce can have a STRAND of hair on her head and still be fine," Kelly told TMZ as she was leaving Madeo in L.A. last night.

But it's not like Beyonce revolutionized women's hair fashion when she decided to hack off her locks -- 'cause as Kelly tells us, "We have been rocking short haircuts since the beginning of time."

In fact, Kelly had a pretty short 'do way before Beyonce did -- and looked great -- but even Kelly admits it wasn't that original of an idea at the time.
