The 37-year-old model-actress, who has two adopted daughters, took to Twitter to share her delight after receiving the honour.
"Beautiful people... 'The Mother Teresa International Award' I received last night. Precious," Sen posted along with a photo.
"What an overwhelming feeling to receive an award named after 'Mother' and with past recipients like his holiness Dalai Lama and Malala Yousafzai," she tweeted.
During the Miss Universe pageant of 1994, Sen had won appreciation by expressing admiration for Mother Teresa.
