The 23-year-old singer wants to have some "private romantic time" with the 18-year-old star ahead of his 19th birthday next Friday as part of the first steps of the pair getting back together following their split earlier this month.
Taylor and Harry are expected to seal their reunion at the NRJ Music Awards in Cannes this Sunday – where One Direction are nominated for International Group of the Year – and a source revealed the blonde beauty wants "no expense to be spared" when she whisks Harry away.
A One Direction insider told the Daily Star newspaper: “The lads are planning to hang out together enjoying Cannes – and they also want to get to Paris.
“But Taylor is desperately trying to make arrangements for her and Harry to slip away and have private romantic time.
“She has got a boat on standby ready for them to sneak off.
“Taylor thought a boat would be the perfect getaway as photographers can’t follow them.”
The 'I Knew You Were Trouble' hitmaker has reserved a small private villa in the town of Mougins, four miles north of Cannes, but Harry's "main focus" is said to be spending time with his bandmates Zayn Malik, Liam Payne, Louis Tomlinson and Niall Horan.
The insider added: “It’s all up in the air as Harry’s main focus is being with his band.”
But it would not be the first time Taylor and Harry went on a yacht after the One Direction singer hired a sailboat to take them to two private islands during their romantic break in the Caribbean at new year, but the holiday ended in disaster when they split after having an argument.
A source said at the time: "Harry and Taylor kept getting hassled for pictures by fans on the island so he hired a yacht for two days and one night to take them to two private islands.
"He organised snorkelling and a chef to cook gourmet meals when they wanted."
