The former lovebirds are both confirmed to attend the ceremony at London’s O2 Arena following their shock split in December.
Harry is performing the official Comic Relief single – a cover of Blondie’s One Way Or Another – with his One Direction bandmates, while Taylor is also in talks to take to the stage.
The pair narrowly avoided each other at the NRJ Awards in Cannes last month, so this could be their first (and very awkward) meeting since their break-up.
Talking about their last near-meeting, a source told The Mirror: “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.”
One Direction are up for Best British Group, while Taylor has been nominated for Best International Female Solo Artist.
Here’s hoping they kiss and make-up backstage. We’ll be keeping our eyes peeled! RM
