Tiger Woods is standing by his girlfriend, Vanessa Trump, after she publicly announced her breast cancer diagnosis.

“Tiger has been very supportive of Vanessa through all of this and is really just focused on being there for her,” an insider told Page Six on Thursday.

The source further said, "He’s proud of how positive she’s stayed and how she’s handling everything so far. She’s been so strong and he truly believes she’s going to be okay. "

"He’s just trying to support her however he can right now," added a tipster.

On Wednesday, May 20, Vanessa announced that she had been diagnosed with breast cancer.

“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,” the former model penned on her Instagram handle.

"I am staying focused and hopeful while surrounded by the love and support of my family, my kids, and those closest to me," added the mother-of-five.

For those unversed, Tiger confirmed her romance with Vanessa in March 2025.

“Love is in the air and life is better with you by my side!” the pro golfer wrote on X while sharing two loved-up photos of himself with Vanessa.

“We look forward to our journey through life together,” Tiger added. “At this time we would appreciate privacy to all those close to our hearts.”

It is pertinent to mention here that Vanessa is a mother of five kids, whom she shares with her ex-husband, Donald Trump Jr.
