The 24-year-old will be appearing on the show's seventh season, which began airing the blind auditions section on September 22, reported MTV online.
The show will properly begin at the end of October when Swift will be joining the show as an advisor. She will be working alongside fellow advisors Stevie Nicks, Gavin Rossdale, Little Big Town and Alicia Keys.
Swift will be taking up the advisor position which was last occupied by Coldplay's Chris Martin last season. Swift will be advising all the competitors, regardless of their coach and team.
"Way excited about being a key advisor on NBC The Voice," she posted.
