2:50 PM PT -- Gavin's rep tells us he's actually wearing 2 rings, but neither is a wedding band. She added ... Gavin's worn them for years, and they have no connection to Gwen.
Gavin Rossdale's holding on to his marriage with Gwen Stefani ... or so it seems.
The Bush frontman was pumping gas Sunday in Studio City ... doing his part to keep a low profile, shades and all. Pretty unassuming ... except for that wedding ring that screamed, "I'm not over Gwen."
TMZ broke the story ... Gavin and Gwen finalized their divorce in April 2016, meaning it's been nearly 2 years since the split and he's STILL wearing his wedding band.
Gavin reportedly continues to wear it for his kid's sake. So much for a sweet escape.
