Weather conditions have been pretty frightful for folks all over the U.S. this week, but in Taylor Swift's world, things are starting to heat up. The 23-year-old country crossover singer hit the slopes with One Direction's Harry Styles and another celebrity couple last weekend for a little R&R. You would be hard-pressed to find a more musical double date than the one that went down between Swift and Styles alongside Justin Bieber and Selena Gomez. The four young entertainers hit the slopes at the Canyons resort in Park City, Utah just before Christmas.

Both Swift and 18-year-old Styles are seasoned skiers, so they started working the mountain right away, according to People. Gomez, on the other hand, didn't have much hidden skill. She took a beginner's ski class to get the hang of things. Her on-again boyfriend Bieber prefers snowboarding, so he cruised down the mountain on his board with his body guards in tow.

Although the couples took the trip together, they stayed in two separate rental houses. The 'Begin Again' hitmaker was spotted sharing a cozy lunch with Styles at the resort's Red Pine Lodge.

We're not sure how long Swift can manage to keep tight-lipped about her time spent with Styles. If this recent ski trip is any indication, the two young singers are getting pretty serious! Maybe we'll have to wait until she writes a song about him to find out the real story.
