Hailey Bieber‘s got fans asking “What Do You Mean?” when it comes to a recent style choice … ditching her wedding ring while out in New York City on Friday.

The model stepped out in the Big Apple without her husband — and without her bling … wearing a light brown trench coat and raising her hand next to her face in the pics.

Eyes were drawn more to the hand than to the ensemble, though … when many realized she wasn’t wearing her wedding ring.

Of course, we dove into all behind-the-scenes drama in Hailey and Justin‘s marriage in our new documentary “TMZ Investigates: What Happened to Justin Bieber” — now streaming on Tubi and YouTube … and we made clear their marriage has never been all sunshine and roses.

However, Hailey mitigated the gossip with her accessories on Saturday … including sharing a mirror selfie with the ring back on.

Keep in mind, the mirror’s flipping the image … so, the ring is in fact on that finger on her left hand — crisis averted, it appears.

As you know … lots of fans are worried about Justin these days — including therapist Dr. Jenn Mann — after a series of Instagram rants, tense moments with the paparazzi and financial issues we uncovered in our documentary.
