Mariah Carey is vacationing in Aspen with her billionaire boyfriend James Packer and her 4-year-old twins Moroccan and Monroe.

The 45-year-old "All I Want for Christmas Is You" singer posted several photos of herself enjoying vacation with her children and 48-year-old beau on Instagram, according to People.

Some of the snapshots she posted to the social media site include her decorating gingerbread cookies, making snowballs and cuddling up indoor by the fire wearing Hello Kitty pajamas. There also was a video posted of the singer, who is seen sledding down a small snowy hill.

She also posted a few photos posing with Packer, whom she began dating in June. Just five months after linking up, she decided to move in to the billionaire's Beverly Hills home.

In one photo of the bundled-up couple, Packer is seen wrapping his arms around Carey's waist. The caption for the photo reads, "#icantski #skilesswonder."

Earlier this month the singer checked into a New York hospital to be treated for the flu, TMZ reported. She was pumped full of fluids and vitamins to offset her illness.

"She seemed under the weather, but pulled through," a source said. "She was on time, did all her press and [gave] a presentation. She usually has a reputation for being a diva, but I guess when she has the flu, she's on her best behavior."

The night before her hospitalization, Carey had attended Pier 1 Imports' pop-up book installation in New York.

Carey just finished up a run of Christmas shows at New York's Beacon Theater, which began Dec. 8 and ended on Dec. 18.

The singer released her last album, "Me. I Am Mariah . . . The Elusive Chanteuse," on May 23, 2014. The album, which topped the U.S. Top R&B/Hip-Hop Albums chart, produced the singles "#Beautiful," The Art of Letting Go," "You're Mine (Eternal)" and "You Don't Know What to Do."
