Rita Ora is making the best out of New York City's "polar vortex".

The 23-year-old pop star is in Manhattan, where temperatures Tuesday dropped to a frigid seven degrees Fahrenheit.

Despite what meteorologists have dubbed a "polar vortex" - an arctic cyclone of cold air - whipping through the metropolitan, Rita was showing off on Instagram her new "backless jacket".

"1 way to wear a Parker on the coldest day of the Year in NYC. Cut it in 2! #Booooom #Backlessjacket." the singer captioned a photo of herself in her winter ensemble (sic).

The star may not be in freezing temperatures for long, however.

Recent reports suggest the British singer may soon be moving to sunny Los Angeles to be closer to boyfriend Calvin Harris.

"He believes they can make their relationship last if they both fully commit to it," a source told the Daily Star, adding that the DJ had asked her to move into his US pad.

"Rita took her time making the decision. But she does spend a lot of time in LA anyway and has friends there. So in the end she knew it was the right thing to do," the source continued.

Spokespersons for the couple have yet to confirm the report.

Calvin and Rita went public with their relationship last summer.
