Instead of rocking her signature slightly-messy bob, Rinna stepped out on Andy Cohen's late-night show with unexpected bangs and longer hair that fell way past her shoulders.

The sleek 'do definitely suited the 54-year-old mother of two, but it also definitely took some getting used to.

Of course, the star didn't just grow her hair out overnight -- her hairstylist revealed on Instagram that Rinna's longer locks are thanks to extensions from Hidden Crown Hair. He called her a "femme fatale!"
