'Tis the season ... to show off your really cool nails!
Lily Allen is definitely feeling the Christmas spirit -- the singer posted a picture of her awesomely festive nails on Thursday, tweeting "Best nails @nailsbymh #lolidays #sicklife," with the photo.
The "5 O'clock" singer's polish included a Santa Claus, reindeer, mistletoe, snowman and candy canes. Who needs an "ugly sweater" to celebrate when you have a holiday manicure?
