Taylor Swift performs romantic concert

Taylor Swift performed a private concert on the River Seine.

The 'I Knew You Were Trouble' singer - who split from One Direction star Harry Styles earlier this month - fled Cannes in the south of France immediately after the NRJ awards last weekend to sing on a romantic cruise in Paris.

The newly single 23-year-old star was spotted performing some of her biggest hits at a private live gig for a group of lucky fans on board the Yachts de Paris Mirage cruise on Monday night (28.01.13), according to EOnline.com.

Taylor's intimate concert came a day after she was spotted enjoying the city's best-known sights, including the Eiffel Tour with her actress pal Hailee Steinfeld.

After successfully avoiding her most recent ex-boyfriend on the red carpet in Cannes, Taylor flew to Paris for a girls' day out on Sunday (27.01.13) with the 16-year-old 'True Grit' star.

She later posted a message, insisting she isn't down in the dumps after splitting from the 'Kiss You' singer, saying: ''Had the best day off in Paris, meandering around, laughing hysterically with @haileesteinfeld''

The country singer reportedly went out of her way to avoid running into her ex-boyfriend on the red carpet at the awards show by delaying her arrival by 25 minutes to avoid an awkward run-in.

A source previously said: ''It was very carefully timed so they didn't do the carpet at the same time.

''Taylor didn't do any backstage interviews and didn't use a dressing room - she changed at the hotel because she didn't want to see Harry at any point. ...Things were timed to keep them apart and for it to not become a big media circus.''
