Chappell Roan shared a sweet tribute to Brigitte Bardot after the French film legend died over the weekend … and she yanked it from Instagram just as fast after the singer learned more about the controversial icon.

Here’s the deal … Brigitte died at the age of 91 — and among those who shared their sorrow was Chappell, who wrote … “She was my inspiration for ‘Red Wine Supernova.’ Rest in peace, Ms. Bardot.”

Seems CR was only aware of Brigitte as a French blonde bombshell and her tireless work to protect animals … and not so much about her outspoken xenophobia and homophobia.

Clearly, word got back to Chappell … and she replaced the tribute with a mea culpa, writing “Holy s—. I did not know all that insane s— Ms. Bardot stood for. Obvs, I do not condone this. Very disappointing to learn.”

As you know, Chappell is a prominent queer pop star and major LGBTQ+ advocate … and since Brigitte made several homophobic remarks in books and interviews over the years — along with anti-immigrant statements — the tribute was hard to square with CR’s fans!
