Cyrus will take over the house of one lucky fan to host an MTV special on Dec. 31.
The winning fan — someone who spent 2008 helping to improve the lives of others — will get to spend some quality time with the Hannah Montana star. After Cyrus surprises the fan by showing op on her doorstep, they will spend the day hanging out together, participating in activities for the fan’s favorite charity and visiting friends.
The fan will also get gifts from the singer and a performance that will be broadcast straight out of her bedroom.
Cyrus’ brother’s band, Metro Station, will also perform.
The 90-minute special, "FNMTV Presents: A Miley-Sized Surprise," airs live at 8 p.m. EST with an encore presentation featuring a live countdown from NYC’s Times Square at 10:30 p.m. EST.
