Jessie J has opened up about amount she has sacrificed to ensure she doesn't disappoint her fans.

The popular singer often has a busy schedule and falling ill or being late for events can put important itineraries out of sync.

Speaking to The Sun, the 'Domino' star admitted that she has given up on a lot of social time in order to stay fit and healthy for concerts and other commitments. She said:

"You are under pressure to always be healthy because there are days in your diary that people have been looking forward to for months. It's really hard when the fans think it's personal but you can't decide when you are sick."

She continued: "So I have literally sacrificed so much in my life where I don't really get to see my friends that much. I don't go out very often, because I want to stay healthy while I am working and I think it's important."

The former Voice UK coach added that when she does go out, she doesn't imbibe much alcohol.
