The concert marks Rascal's third appearance at the festival, which is now in its eighth year.
Basshunter, aka Jonas Altberg, will perform his first major UK gig since leaving the Celebrity Big Brother house. His appearance last year included dancers with welding gear and metal bikinis.
The pair are the latest in a long list of acts who are already confirmed for the event, including JLS, Pixie Lott, Chipmunk and Alexandra Burke.
This year's T4 On The Beach takes place on July 4. Tickets have now sold out.
