Ivanka Trump is “happy” about her ex-sister-in-law’s new romance.

The businesswoman reacted to Vanessa Trump and Tiger Woods going Instagram-official on Sunday with a supportive comment.

“So happy for you both,” the 43-year-old gushed, adding multiple smiling emojis.

Woods, 49, shared two loved-up snaps with Vanessa, 47, over the weekend, nearly two weeks after Page Six confirmed their reported relationship.

“Love is in the air and life is better with you by my side!” the professional golfer captioned the carousel. “We look forward to our journey through life together.

“At this time we would appreciate privacy for all those close to our hearts,” he concluded.

While Vanessa has yet to share her own post, she added Woods’ slideshow to her Instagram Story.

A source explained to us earlier this month why the pair make a “good match.”

The insider said, “They have a lot in common. They’ve both gotten used to public scrutiny. They both know how to keep their private life private. They’re both parents. … They’re level-headed, they like to avoid drama, they share a lot of the same values.”

Vanessa was previously married to Ivanka’s brother Donald Trump Jr. from 2005 to 2018, and the former couple share five children — daughter Kai, 17, son Donald III, 16, son Tristan, 13, son Spencer, 12, and daughter Chloe, 10.

During their time together, Ivanka gushed to People about Vanessa’s “amazing” parenting skills, calling her family member an “inspiration.”

She said, “My sister-in-law Vanessa is a machine. … She has five children and she’s Wonder Woman to me.”

After Vanessa and Donald Jr., 47, finalized their divorce, he moved on with ex-fiancée Kimberly Guilfoyle and is now dating Bettina Anderson.

Woods, for his part, split from then-wife Elin Nordegren in 2010 amid his headline-making cheating scandal.

The exes now co-parent daughter Sam, 17, and son Charlie, 16.
