Demi Lovato is the new face of CORE Hydration campaign

Demi Lovato has been forced to reschedule the South American and Mexican leg of her Tell Me You Love Me tour (see below) and is also announced as the face of CORE Hydration's new campaign.

The campaign is set to launch this spring and will feature an in-depth look into her lifestyle and how CORE’s perfectly pH balanced water helps to maintain all aspects of her life.

Lovato, who actively champions body confidence and positivity, also took to social media on Friday to share a powerful message with her fans as she shared revealing photos. She told her followers: 'The boomerang smoothed out my legs. The point is, I have cellulite just like the other 93% of women do.

'Cellulite and yet I still love myself.

'What you see on Instagram isn't always what it seems to be. Let's embrace our real selves. #iloveme.'

The star has also been forced to reschedule the South American and Mexican leg of her Tell Me You Love Me tour.

Taking to Twitter to share the news last night (April 10), Lovato wrote: "I'm absolutely heartbroken that I have to make this announcement today... due to production issues we have to move the South America #tellmeyoulovemetour dates ...

"Ecuador, Costa Rica, and Panama I'm devastated we had to remove those shows ... Truly hate that we have to do this & we tried our best but there were some unforeseen production issues. If you're unable to make the new dates we will give you a full refund ... I'm so sorry. I promise it will be worth the wait & I hope to see you. I love you guys so much! (sic)"
