A British mom says Alexa became the Grinch that stole Christmas.

Lizzy Nuttall, 41, contends the Amazon personal assistant announced that her daughter’s Christmas present had arrived — and that the camera she wanted was inside, according to The Sun.

“When we went into the kitchen yesterday, the yellow light was on to say there was a message. Then it blurted out, ‘Parcel arriving — Instax,’“ Nuttall told the newspaper.

Her 10-year-old daughter, Alice, clearly heard the news, she said.

“I think Alexa has turned into the Christmas Grinch,” the mom said. “Now we’ll have to get Alice another gift because she hasn’t got a surprise.”

Nuttall said she wanted to warn other parents about Alexa’s big mouth.

Amazon had said that the beginning on Nov. 17 Alexa would stop revealing the names of items likely to be gifts, The Sun reported.
