Mariah Carey gets $300,000 for a one-hour store visit

Mariah Carey is like Santa--she always delivers in time for the holidays.

Our favorite little Christmas elf is already spreading holiday fear wherever she goes, this time making demands for an appearance which could land her on the naughty list.

Carey’s kicking off December with an appearance Tuesday night at a Pier 1 pop up store in New York, where Confidenti@l has learned she’s being paid a whopping $300,000 to attend the event for just one hour.

“Let’s call it 45 minutes,” laughs our source, who adds that the “Hero” singer also had a few demands about her appearance. “She specifically wanted (it noted) that she was ‘appearing’ not ‘performing.’ They would have loved her to perform but just getting her is worth it.”

Our insider adds that Carey gave final approval on the invite before it went out, requesting that she be called “The Queen of Christmas,” at the “Pier 1 Imports: Christmas Pop-Up Storybook” at 503 Broadway. The invite didn’t stop there, reminding potential guests that they will be joining “the biggest selling female recording artist of all time,” who we hear will arrive around 7:30 p.m. — more than 90-minutes after the event starts.

“She has to do nothing. Show up, wave a little, talk to a few pre-approved outlets. She’s in town so why not make all the money you can?” says our source.

Carey is also in town to appear at a Dec. 5 concert at the Prudential Center in New Jersey, “Hot for the Holidays featuring Busta Rhymes & Friends” and has been doing promotional appearances while here. But since holding a grudge against one network that burned her last year, Carey --who celebrates Christmas with the enthusiasm of a dozen sprightly reindeer on the loose -- appeared on Nov. 27 on a pre-taped “Good Morning America” interview segment with Amy Robach to promoting her new children’s book, “All I want for Christmas is You.” The songstress was also there to push her new movie, “A Christmas Melody,” set to air on the Hallmark Channel.

We’re told she chose ABC to hawk her goods in the segment taped on Nov. 11, because of last year’s debacle with NBC, when disgruntled techies working for the Peacock network leaked a painful vocals-only recording of her Rockefeller Center tree lighting appearance. Apparently they were miffed because she had kept them waiting for three hours in the cold. Carey did appear on a float at the Thanksgiving Day Parade last week, which aired on NBC, but we’re told that’s because it was a Macy’s production. No word yet on if Carey will change her mind and schedule an NBC appearance.

According to a rep for Pier 1 “We are very excited to be working with Mariah Carey this holiday season, but we do not comment on private business matters."

A rep for Carey declined to comment.
