Heidi Klum -- Still Wearing Wedding Ring, Too

Seal isn't the only one clinging to symbols of his crumbling marriage -- Heidi Klum was also still wearing her wedding ring yesterday in L.A ... but with a twist.

The pic was snapped as Heidi was leaving the set of "Germany's Next Top Model" (yes, it's shot in LA) -- and she was still sporting either her wedding band ... or her engagement ring. If it was the engagement ring though, Heidi was hiding the giant diamond.

It's the first time we've seen Heidi's face since news broke about her split from her husband -- her full face at least.
