Singer Demi Lovato has sent her best friend Selena Gomez a message of support following the news Justin Bieber's ex-girlfriend spent two weeks in rehab last month (Jan14).
The Come and Get It hitmaker voluntarily checked herself into a facility in Arizona, and while her spokesperson confirmed her stay at the center, there was no comment on what she underwent treatment for.
As news of Gomez's surprise rehab stint made headlines on Wednesday (05Feb14), her longtime pal Lovato took to Twitter.com to send her friend a message of encouragement.
She wrote, "Weakness is living in denial. Only the strongest people ask for help."
Lovato is all too familiar with facing personal problems while in the spotlight - she spent three months in rehab for addiction issues and an eating disorder in 2010 and 2011.
