Demi Lovato has admitted that she is trying "everything she can" to not succumb to illness on tour.

The former X Factor USA judge is currently on her North American Neon Lights tour as she mines her 2013 record 'DEMI' for material.

However, Lovato has already fallen ill despite the jaunt only opening on February 9.

To avoid any potential cancellations, the 'Skyscraper' star has been trying different remedies to stave off illness. She wrote on Twitter:

"Doing everything I possibly can to get better by tomorrow... Humidifier, Thera Flu and steam inhaler!!!"

The next date on the tour is due to take place tonight (February 17) in Grand Prairie, Texas.

Support on the jaunt meanwhile comes from Little Mix, Cher Lloyd and Fifth Harmony.
