Michael Douglas is still sporting his wedding ring ... and wants everyone to know he's STILL MARRIED to Catherine Zeta-Jones, despite reports he split from his wife.
Douglas was in Berlin over the weekend for the premiere of his movie "Behind the Candelabra" ... when a reporter asked him why he was still wearing a ring on his wedding finger.
Michael's response -- "I'm married."
Just last week, reports surfaced that Douglas and Zeta-Jones were taking a break after 13 years together ... and the break was, in part, due to the stress from Douglas' battle with cancer and Catherine's struggle with bipolar disorder.
But after this weekend, it's clear Douglas isn't ready to throw in the towel just yet.
