Ivanka Trump sent a touching response to her former sister-in-law, Vanessa Trump, after she revealed her breast cancer diagnosis.

“Praying for your continued strength and a swift recovery,” the ex-presidential advisor, 44, commented on Vanessa’s Instagram post.

“Love you mama,” Ivanka — who is a sister to Vanessa’s ex-husband, Donald Trump Jr. — added.

Ivanka’s supportive message came momentarily after Vanessa took to Instagram, publicly sharing her “personal health update.”

“I’ve recently been diagnosed with breast cancer. While this isn’t news anyone expects, I’m working closely with my medical team on a treatment plan,” she wrote.

Vanessa then thanked her doctors for performing a “procedure” on her earlier this week.

“I am staying focused and hopeful while surrounded by the love and support of my family, my kids, and those closest to me,” the mom of five, 48, added.

“Thank you for your kindness and support it truly means more than I can express. I kindly ask for privacy as I focus on my health and recovery,” she concluded.

Vanessa shares five children with her ex Trump Jr.: daughters Kai, 19 and Chloe, 11; and sons Donald III, 17, Tristan, 14, and Spencer, 13.

The businessman, also 48, and Vanessa were married from 2005 to 2018.

The former model was last publicly seen celebrating her daughter Kai’s high school graduation last Friday.

At one point, Vanessa and Trump Jr.’s fiancée, Bettina Anderson, hugged and appeared friendly.

Vanessa’s boyfriend, Tiger Woods, also attended the graduation — showing up late and leaving early.

Last week, the pro golfer, 50, was photographed getting off a private plane following his month-long rehab stint after being arrested on DUI charges.
