When you're going through a hard time, it's important to know your friends are there for you - and Demi Lovato is definitely there for her pal Selena Gomez.
The life of a pop star can be hard at times, and last month Selena checked into an Arizona rehab centre and spent two weeks getting some help for an unspecified issue.
At the end of 2013 the Come and Get It hitmaker scrapped her Australian tour so she could "spend some time on herself", and some reports suggest she headed to the centre to get help with emotional issues.
As news of the singer's stay at the facility spread, her friend Demi was on hand to offer some words of support.
Taking to Twitter, the Heart Attack singer wrote, "Weakness is living in denial. Only the strongest ask for help."
Demi's no stranger to having to ask for help herself, after spending time in rehab centres in 2010 and 2011 to deal with addiction issues and an eating disorder.
Hopefully Selena's not going through anything too serious and we'll see her back at her best before too much longer.
