The US First Lady debuted a new style with a fringe last week, and though it has attracted much praise, the Chanel designer isn't a fan.
He told French TV show 'Le Petit Journal': ''I don't understand the change of hair. I adore Madame Obama, I love her. But there is a news reader at LCI which has this haircut.
''Frankly, this doesn't suit her. The fringe was a bad idea, it's not good.''
During the interview, the outspoken designer also claimed his fingers shrink during the day - leading to him losing his jewellery on a regular basis.
He said: ''It's a non-explainable phenomenon. If I make a zealous gesture to someone then they receive a ring right in their face.''
It was recently claimed that 78-year-old Karl enjoys pretending to be a statue in the streets of Paris.
The Kills star Alison Mosshart revealed: ''One time, I was at Café de Flore in Paris and he was sitting outside on a bench on the pavement almost like a statue - it was the most amazing thing.
''People kept walking by, sitting down next to him and having their photos taken and then they'd get up and walk away. He didn't say a word.''
