The 18-year-old singer was dumped by the 'I Knew You Were Trouble' hitmaker Swift earlier this week, following a two-month whirlwind romance, reported Sun online.
Just 24 hours after the split, Styles shared a hot tub with TV presenter Hermione Way while on holiday on Richard Branson's Necker Island and she says the the singer seemed very content with his life.
"I didn't know what had happened. He seemed happy to me. I had a lovely time. Harry is a charming fella," the 27-year-old beauty said.
And it seems Styles is making sure he enjoys his time as a bachelor as he is planning a boys' holiday with teen pop sensation Justin Bieber, who recently split from on/off girlfriend Selena Gomez.
"The lads talked about a boys' trip when they were going out with the girls, but it was never on the cards. Now they're footloose and fancy-free, they want to make it happen. They might not be old enough to legally drink but that won't stop them," a source said.
