Lady Gaga Reveals Where She'll Spend Christmas

Little Monsters saw how Lady Gaga celebrates Thanksgiving during her lavish TV special, and now we know where Mother Monster will spend the holiday season.

"Well I'll be in Japan right up until Christmas day," Gaga told earlier this month. "So I'll be eating with all my Japanese Little Monsters. I like shabu shabu [a form of Japanese hot pot]."

On Tuesday (December 20), the singer tweeted about her trip there. "Just arrived in Tokyo!" she wrote, including a photo of herself sitting in her hotel room. "So happy to see my Kawaii Monsters! #SleepyGaga bedtime. I'm a professional napper today."

She kicked off the gifting season with her holiday-themed pop-up store and window display, Gaga's Workshop, at Barneys New York. She and stylist Nicola Formichetti gave fans an idea of what the pop star would want from Santa with Mother Monster-inspired products like head-shaped candles, leather jackets, her favorite books and chocolates shaped like shoes.

The singer is expected to land Stateside on December 31, just in time for the 40th annual "Dick Clark's New Year's Rockin' Eve.". She's one of the many acts lined up for the event, including Nicki Minaj, Justin Bieber, LMFAO and Florence and the Machine. The show will be anchored by "American Idol" host Ryan Seacrest, with help from Fergie and Jenny McCarthy.

The busy holiday season caps off an even busier year for Lady Gaga, who happened to be MTV News' Top Newsmaker of 2011. She tirelessly released singles, videos, personas, a chart-topping album (Born This Way) and scooped up awards at seemingly every show from the Grammys to the VMAs. She was also our #5 Best Artist of 2011, and her disco empowerment track, "Born This Way," boasted the #5 spot on the Best Songs of 2011 list as well.
