Although he is not mentioned by name in the song, "Obsessed" explores Mariah's dilemma regarding constant claims of a prior relationship from rapper Eminem. In the music video, Mariah plays both herself and the stalker. After several photographs of Carey dressed as the stalker were leaked, tabloids immediately compared Carey's costume to Eminem's usual attire.

Someday hey hey
Boy you're gonna pay 'cause baby I'm the one who's keeping score
You'll change your mind and call my name
Soon as you find they're all the same
And when you find yourself alone
Don't come back crying
You should have known

In 1999, Carey bought Marilyn Monroe's white lacquered baby grand piano. She paid over $600,000 for the one-of-a-kind treasure. Mariah has publicly acknowledged Marilyn Monroe as one of her idols, and her daughter Monroe is named after Marilyn.

Mariah Carey's legs are insured for $1 billion. Billion. Not Million. Billion, with a "B". That's $500 million per leg. She took this extraordinary step after becoming the face of Gillette's "Legs of a Goddess" Campaign in 2006.

Mariah spent two weeks under psychiatric care in 2001 following a mental breakdown. During that time, she was diagnosed with bipolar II disorder. In 2018, she opened up about the diagnosis, saying, "Until recently I lived in denial and isolation and in constant fear someone would expose me. It was too heavy a burden to carry and I simply couldn't do that anymore. I sought and received treatment, I put positive people around me and I got back to doing what I love--writing songs and making music."

Who's gonna talk to me on the phone
Till the sun comes up
Who's gonna take your place
There ain't nobody better
Oh, baby baby, we belong together

It earned ten Grammy Award nominations in 2006-07: eight in 2006 for the original release (the most received by Carey in a single year), and two in 2007 for the Ultra Platinum Edition.

In Precious (2009), Mariah plays a social worker who helps a 16-year-old living in Harlem who has been subjected to physical and emotional abuse by her family. The film won the Audience Award and the Grand Jury Prize for best drama at the Sundance Film Festival and was nominated for six Academy Awards.

"All I Want for Christmas Is You" achieved instant critical success, with The New Yorker calling it "one of the few worthy modern additions to the holiday canon." The song remains Carey's biggest international success, reaching number one in numerous countries, including Australia, Canada, France, Germany, and the United States.

Let me fill your heart with joy and laughter,
Togetherness, well it's all I'm after,
Just call my name, and I'll be there
