Humour or humor (see spelling differences) is the tendency of particular cognitive experiences to provoke laughter and provide amusement. The term derives from the humoral medicine of the ancient Greeks, which taught that the balance of fluids in the human body, known as humors (Latin: humor, "body fluid"), control human health and emotion.

People of all ages and cultures respond to humour. The majority of people are able to experience humour, i.e., to be amused, to laugh or smile at something funny, and thus they are considered to have a sense of humour. The hypothetical person lacking a sense of humour would likely find the behaviour induced by humour to be inexplicable, strange, or even irrational. Though ultimately decided by personal taste, the extent to which a person will find something humorous depends upon a host of variables, including geographical location, culture, maturity, level of education, intelligence and context. For example, young children may favour slapstick, such as Punch and Judy puppet shows or cartoons such as Tom and Jerry. Satire may rely more on understanding the target of the humour and thus tends to appeal to more mature audiences.

She has received an International Indian Film Academy Award and Stardust Award for Best Female Debut in 2010, for her role in Aladin.

In March 2006, Fernandez was crowned the Miss Sri Lanka Universe 2006 and subsequently represented Sri Lanka at Miss Universe 2006 where she did not place. From there she began receiving offers to go to India for more modelling, and she got selected for a Bollywood film.

Fernandez made her acting debut in the 2009 Bollywood fantasy movie Aladin opposite Ritesh Deshmukh. She played a character inspired by the Disney Princess character of Jasmine. 2010 saw her once again appearing alongside Ritesh Deshmukh in the romantic comedy Jaane Kahan Se Aayi Hai. She also made a cameo appearance in Sajid Khan's Housefull in the song 'Dhanno' which was a big success. Fernandez almost gave up acting during this time because good roles were not coming to her.
