Taylor Swift isn't letting a little thing like heartbreak slow her down, professionally speaking. We know, she always turns romance lemons into song lemonade, but Diet Coke's new partner followed up her performance at the NRJ Awards in Cannes, France over the weekend (where she steered clear of her most recent ex, One Direction's Harry Styles) with a private show on the Seine River.

Swift was sightseeing with Hailee Steinfeld in Paris before boarding a boat and performing on Jan. 28, according to E!

Swift was decked out in basic black and cradled her red guitar while performing for fans on the Yachts de Paris Mirage cruise around the romantic city. It's a shame she didn't have anyone to share it with, at least in the romantic let's-hold-hands-and-traipse-across-a-foreign-city-way. She actually already did that in her French-themed video for 'Begin Again.'

After a trip to Spain and France and a brief stop in England, Swift is now back in America to prep for her 2013 Red Tour. She tweeted Monday night, "Thank you to all the fans in France and Spain for making this trip so lovely. Headed back to U.S. now!"
