The illustration of cosmic acceleration under two interacting dark energy models (pilgrim dark energy with Granda-Oliveros cutoff and its generalized ghost version) in the DGP braneworld framework is presented. In the current scenario, the equation of state parameter, deceleration parameter, -
plane and statefinder diagnosis are investigated. The equation of state parameter behaves like the phantom era of the universe. The deceleration parameter shows the accelerated expansion of the universe in both models. The cosmological planes, like
-
, and the statefinder correspond to the
CDM limit. To conclude, we remark that our results support the phenomena of pilgrim dark energy and cosmic acceleration. Also, the results are consistent with observational data.
