Harry Styles and Taylor Swift will be kept in different backstage sections by bosses of the BRIT Awards at the O2 tonight (20.02.13).
One Direction's Styles and his band will have their own dressing room in one part of the Greenwich venue, while his ex-girlfriend Swift will be kept in a completely different section.
A source said: "No one wants anything awkward to happen. Taylor and Harry are definitely being kept well apart.
"Taylor is near Robbie Williams, Justin Timberlake, Mumford & Sons and [host] James Corden in one area.
"Harry is down a different corridor with an extra-large room for himself and the other 1D lads."
Since Styles and Swift split over New Year they have both been careful to avoid each other, for instance deliberately arriving at different times to the NRJ Awards in France.
Tensions between the pair are thought to be running high after Swift appeared to mock Styles's English accent when she opened the Grammy Awards in Los Angeles earlier this month.
Styles, 19, will be performing his new Comic Relief single One Way Or Another with One Direction - who are up for Best British Group - at the BRITs.
Swift, 23, is up for the International Female Solo Artist gong and is expected to perform her track We Are Never Ever Getting Back Together at tonight's show.
