The 'Radio' singer's name appears alongside fellow performers Demi Lovato and Daughtry on tickets for the taping of the programme tomorrow (March 15), according to Idolator.
However, it is thought that Del Rey's performance will be pre-recorded for a future results show.
Del Rey made her live TV debut in the US earlier this year on Saturday Night Live, attracting a large number of negative reviews.
She will perform at this year's Isle of Wight Festival on Friday, June 22, alongside the likes of Feeder and Elbow.
