Pair to sing Telephone
The pair are said to have finalised the plans when they met at the Grammys on Sunday.
Lady Gaga, 23, has already been confirmed to sing at the ceremony and Beyoncé is believed to be accompanying husband Jay-Z, who is also on the bill.
‘It would be the perfect opportunity to perform their duet Telephone live to fans,’ a source tells Metro.
As well as working on Telephone, the pair have collaborated on the track Video Phone.
Lady Gaga, real name Stefani Germanotta, teamed up with Sir Elton John, 62, at the Grammy Awards for a mash up of Your Song and Speechless.
The Brit Awards take place at London’s Earls Court on 16 February.
