The 35-year-old make-up artist, who was known for her proximity to co-contestant Gautam Gulati in the house, said she is upset with her eviction.
"There were few days left and I wanted to be on the show for some more time. I had been in the house for such a long time and became familiar with the place. I am upset as I haven't expected to be evicted," Diandra told PTI after her elimination.
The bald model is the ninth contestant to be evicted from the show after staying in the house for more than two months.
Actresses Sukirti Kandpal, Deepishikha Nagpal, Minissha Lamba, Nigaar Khan, Serbian model Natasa Stankovic, Mr Gay India Sushant Divgikar, Arya Babbar and 'Roadies' star Renee Dhyani have been previously evicted from the show.
'Bigg Boss 8' hosted by Bollywood star Salman Khan airs everyday on Colors.
