The Bang Bang hitmaker launched the latest leg of her Sweet Talker trek at the end of April (15), but she was struck down by illness last week and instead of partying after her gig in Toronto, Canada on Thursday (07May15), she retreated to her hotel room and turned on a humidifier.

Jessie shared a photo of her less-than-exciting after show activities on Instagram.com and revealed she would be spending her Friday (08May15) on bed rest.

She captioned the snap, "After show (turn) up! This head cold be trying it. Duvet day tomorrow. Goodnight beautiful people! Stay believing in yo self (sic)!"

The singer managed to play through the stuffy sinuses to honour her show in Chicago, Illinois on Saturday (09May15), but by Monday (11May15), the cold was worse. However, the star is determined to hit the stage in Minneapolis, Minnesota on Monday night.

Jessie uploaded a make-up free picture of herself frowning with the accompanying caption: "Fed up of being sick now Face... Been up all night coughing. DAMN YOU TIGGLY (sic) COUGH! Minneapolis I'm still gonna rock my a** off with you!!! Might be a little raspy and bunged up but I'm ready."
