Actress Trisha who is on strict diet regime has collapsed on the sets of Young Tiger Jr NTR's new movie Dammu, says filmnagar sources. Apparently, the actress fell on the sets of Dammu while shooting for a peppy dance number with NTR as she failed to match the energy levels and dancing abilities of the actor. Currently, she is resting at home and will join the sets for the last schedule from Mar 26. However, Trisha is in an optimistic mood and says that NTR's energy levels are unmatchable and he is the best dancer of Tollywood. Also, she assures of coming up with high energy levels this time only to match the power of young tiger.
