The 41-year-old actress, best known for her films like 'Saudagar', 'Dil Se' and 'Bombay', is set to tie the knot with businessman Samrat Dahal, seven years younger to her, in a traditional ceremony near the Nepalese capital.
The wedding ceremony will be a low-key affair with 150 guests and close family friends attending the event, which will be off-limits for the media.
Invites have been sent to President Ram Baran Yadav, Prime Minister Madhav Kumar Nepal, Maoist chief Prachanda and other senior political leaders on the occasion. Former King Gyanendra and his spouse Komal Shah have also been invited for the wedding.
From B-Town, Manisha's friend Govinda and others are expected to attend the ceremony. Grand daughter of first elected Prime Minister of Nepal B P Koirala, Manisha and Dahal, 34, will marry in a 'Swayambar' at the luxurious Gokarna Forest Resort, some 10kms east of the capital, according to family sources.
Dahal, who comes from a business family of Kathmandu, has just returned from the US after completing Masters Degree in Microbiology.
However, the reception, to be held at Hotel Soaltee Crowne Plaza in Kathmandu will be grand and 3, 000 cards have been distributed for the same.
The marriage, which comes two months after the demise of Girija Prasad Koirala, will bring happiness to the Koirala family and Manisha's parents Prakash and Sushila Koirala will host all the ceremonies.
Manisha and Dahal have been seeing each other over the past year and their wedding date was fixed by an astrologer a few months ago.
The actress has evaded marriage over the years and broke off two engagements in the past.
She was reportedly engaged to ex-Australian ambassador to Nepal Crispin Conroy in 2001, but broke up with him soon. Last year too, the grapevine was abuzz that Manisha will wed American speaker and author Christopher Dorris, but that relationship too ended.
