Jessie J Travels While Battling a Brutal Chest Infection

Jessie J keeps it cool in shades while making her way through security at LAX Airport on Saturday (December 6) in Los Angeles.

The night before, the 26-year-old singer hit the stage with Ariana Grande at KIIS FM’s 2014 Jingle Ball.

Sadly, Jessie isn’t feeling so great.

“Current mood. Sick and tired but happy! Go away chest infection you won’t slow me down!” she captioned an Instagram photo. “Well you can but I will try my best for you not to! lol I have countries to fly to and songs to SANG! (Haven’t been this ill in 2 years tho) 😩😂 Soup sleep and laughter!
