ET's Nancy O'Dell recently caught up with the 51-year-old singer in Las Vegas and Dion used the name of her upcoming album, Courage, as a guide for her sweet message to Spears.
"Right now she needs courage, so I'm sending her all my courage, and my inner strength, and my stability, and the love and respect I do have for other artists," Dion said, shortly after a source close to the Spears family told ET that the 37-year-old singer is currently in a facility taking time to care for herself due to the tremendous stress over her father, Jamie Spears', health crisis.
"It's hard sometimes... but, you know, when you go [through] something hard, especially [with] a family member, you find strength within yourself you did not know you had," Dion continued. "I do not know her so personally, but, after a while, when you go through something tough, you come back stronger."
Dion, who will play the final show of her long-running Vegas residency this summer before kicking off a world tour in Quebec City on Sept. 18, also spoke to Spears' contribution to the Vegas music community following her Piece of Me residency from 2013 to 2017. Spears was set to kick of a second residency, Domination, in February, but previously postponed it indefinitely due to her father's illness.
"The artists... there's a place for them, and people want them to be there," Dion said. "...When they come and they perform, they change Vegas for the best."
Dion is far from the only person to publicly show her support for Spears. The pop star's younger sister, Jamie Lee Spears, praised her sibling by sharing an adorable throwback photo, while Spears' boyfriend, Sam Asghari, commended her "absolute strength."
Even Kevin Federline, Spears' ex-husband with whom she shares two sons, told ET through his attorney that he "commends Britney for recognizing that she needs to take a step back."
On Wednesday, a second source told ET that Spears "seems to be on a constant roller coaster and can't get off."
"She finally realized it was affecting her everyday life and even her relationships," the source said. "She wants to feel better and more relaxed and taking time to focus on herself truly is her only option. It has been a rough year. While those closest to her have encouraged her to get help, she finally decided on her own it was time."
