The supermodel took to Instagram to share a sunset selfie with her fiance, writing: "I love you more than I have words to express. Josh, you’re my best friend and my soulmate."
"I can’t wait for forever together. Yes a million times over 💍"
A source close to the couple revealed the proposal happened a few weeks ago "during a romantic weekend together in upstate New York.”
“They’re both overjoyed and happily celebrating. Their hearts are full and they’re excited to build their future together.”
When married, Karlie will become Ivanka Trump's sister-in-law, as Josh's brother is Jared Kushner.
Congrats to the happy couple!
