27-year-old Nisha became the first Nepali actress to reach the 8,848 metre-high summit, according to Tilak Pandey, an official at Tourism Ministry.
Nisha stepped on the summit at about 8 am today having left for the base camp on April 9.
However, her Everest adventure became controversial after it was discovered that she did not have the permission to climb the peak, as the papers showed her as an assistant in a Chinese expedition team.
No climber can go beyond the base camp without expedition permit issued by the Nepalese government.
