USA - The fact that most parents are embarrassing in the eyes of their pubescent children is probably a well-known phenomenon - but even stars are not spared.

Mariah Carey's (56) 13-year-old son, Moroccan, did a livestream on the Twitch platform a few days ago.

As Page Six reported, he was only there for ten minutes when the "All I Want for Christmas Is You" singer unexpectedly came into the teenager's room.

His twin sister Monroe also had the 56-year-old in tow.

"Sorry, Chat, my mom's here," Moroccan said immediately, informing his viewers, who were able to communicate with him via messages.

Many of his fans immediately greeted the Grammy winner via the message function in the livestream.

"Okay, you all need to get out now. Just all go out," the 13-year-old said quickly after Carey and her daughter had spoken briefly.

However, the two didn't leave - the 56-year-old even leaned against her son's chair and looked into the camera.

"Mom, they can see you. They're saying, 'Hi Mariah, I love you!" Oh my God."

Mariah immediately replied to her fans and even said hello, but it was getting too much for her son.

"Can you all please go outside? I love you, but get out of my room!" the teenager blurted out.

A little later, the mother-daughter duo also left the room and left the 13-year-old alone.
