That was quick. America's sweetheart Taylor Swift has reportedly moved on from One Direction star Harry Styles and has a new boyfriend - British singer Ed Sheeran.

According to The Sun, the songstress and Sheeran allegedly had a secret romance last March and apparently rekindled their relationship after the Brit Awards last month.

Sheeran is one of Styles' best friends, so we can't help but wonder what her ex thinks about her reported new relationship?

Swift has famously used her failed romances as song inspiration and has no problem with her musician exes following her example.

She recently told Britain's InStyle magazine, "If I'm gonna write songs about my exes they can write songs about me. That's how it works. I'm not gonna complain about it. I'm not gonna sit there and say, 'I'm the only one who can write songs about this relationship.' It's fair game."
