And to make things worse, the 48-year-old claims the First Lady then declared: "I'll never be able to wear this dress again."
Diva Mariah has been taking a deep-dive into her most shameful memories – and that went right in at No1.
The singing star explained she was at a Christmas tree lighting ceremony at the White House in 2013, when her son Moroccan was two.
She recalled: "Rocky spit up on Michelle Obama's dress, and it was one of the most humiliating things that ever happened to me.
"She was like, 'Thanks to you, I'll never be able to wear this dress again, Rocky. So thank you.'"
But Mariah wasn't finished with the shame trawl, going on to recall how "mortified" she was at stealing Meryl Streep's seat at the Golden Globes in January.
She explained that she accidentally nabbed the seat when Meryl was in the loo, but says the movie legend was "cool" about the mix-up.
"That was so mortifying," she told US telly host Andy Cohen on his show Watch What Happens Live.
"She had spoken to me when I did Precious and she was so sweet, and I was like, 'I can't believe that Meryl Streep was talking about my performance!'
"So, when I sat in her seat, I was like: 'I didn't do that. Please say I didn't do that!'
"But she was like: 'You can sit in it any time!' She was very festive. She was cool about it."
The 69-year-old actress has joked in the past about finding Mariah in her seat, next to director Steven Spielberg.
Meryl said: "B**** stole my seat! There she was next to Spielberg, sucking up. I said, 'No, no, stay there.' I said I'll sit on your lap."
