Halle Berry can't fool us -- that's definitely NOT her wedding ring!

Looking quite bedraggled, the Oscar winner stepped out with daughter Nahla to pick up a cake in Beverly Hills yesterday afternoon, and what caught our attention was the fact that we haven't seen the actress and husband Olivier Martinez together in months! The A-list star was noticeably missing something important -- her striking emerald engagement ring! Yes she's wearing a set of rings but she's definitely NOT wearing the usual ring she wears on that finger!

The Frankie & Alice star and her French hubby used to barely leave each other's sides, but it seems the brunette beauty has been spending more time with her kiddos and less time with her man! In Hollywood, that usually leads to one thing - divorce! Insiders tell X17 it won't be long before the couple pulls the plug on their union.

A source tells us:
    Halle and Olivier's marriage is all but over. They haven't spent time together in months, but Halle isn't ready to go public with the split. That's why she's wearing those gold rings - to distract from the fact she's not wearing her emerald wedding band.

It's understandable that the mother-of-two is trying to keep her relationship troubles under wraps. After all, if she and the Ollie split, this will be her third failed attempt at a happily ever after!

Another insider dishes to X17:
    "Halle is very private; she doesn't need the world to know her third marriage didn't work out. She just wants the kids to be okay and move on."

Has another celeb duo bit the dust? We think so ...
