The 37-year-old singer was a fellow judge with Lovato on season three of The X-Factor back in 2013, and the pair have maintained their friendship, posing together last October at the InStyle Awards.
On Tuesday, Lovato was hospitalized for a drug overdose, sources tell ET, and the news has clearly had an impact on Rowland.
A day after news broke of the 25-year-old pop star's hospitalization, the Destiny’s Child member visited Refinery 29’s 29 Rooms event in Chicago, Illinois, and showed her support for Lovato in a very public manner.
“@ddlovato I [love] you,” Rowland captioned one Instagram Stories photo of a drawing of a lion.
Lovato has a large lion tattoo on her hand, and Rowland decided to copy the look with a temporary drawn-on tattoo. She posted a video of herself getting the ink, writing: “Got you on my mind.”
Rowland is one of many stars lending their support to Lovato in the wake of her relapse and hospitalization. Stars like Ariana Grande, Kim Kardashian West, Lady Gaga, Nick and Joe Jonas, Katy Perry, Justin Timberlake, Bruno Mars and many others have posted their well wishes on social media.
On Tuesday, Lovato’s rep released a statement to ET regarding the singer's hospitalization. “Demi is awake with her family who want to express thanks to everyone for the love, prayers, and support," reads the statement. "Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now.”
