The Sun had previously reported that Brits organisers were having to rearrange rehearsals in a bid to keep the One Direction hunk and Swift apart, despite the pair originally being scheduled to practice their performances today (February 19).
A source told the tabloid: "It was a bit of an oversight to say the least. The original plans were drawn up a while back when Harry and Taylor bumping into each other wouldn't have been an issue.
"But they've had to have a bit of a rethink now. Mumford & Sons were meant to be rehearsing on the Monday with Robbie Williams, Emeli Sandé and Ben Howard - but they were happy to switch.
"It could have caused a bit of a headache if the Mumfords kicked off - but fortunately they played ball."
However, Styles has now told Grazia magazine: "I'm not worried about seeing her at all. She's a sweet girl, you know. I don't have a bad word to say about her."
Speaking of 1D's stint on stage at the bash, Hazza said: "I can't wait for the Brits. We're going to be performing our Comic Relief single, so it's amazing to have such a big platform for that."
The 19-year old also went on to address his close friendship with Radio 1 DJ Nick Grimshaw, telling the publication: "We just get on really well. From the first time we met we just had a laugh.
"There's nothing weird about it. We're both as much idiots as the other one, he's a really, really funny guy."
Harry also hit the headlines this week after discussing Taylor's apparently dig at him during her performance at the Grammy Awards, saying it was "just another good Taylor Swift performance."
