The German model, 45, has been dating musician Tom Kaulitz, 29, for nearly a year and confirmed their engagement on Christmas Eve. Klum, who is also a judge on America’s Got Talent, shared the news with a post on Instagram.
In a black-and-white snap of them, she showed off her diamond ring and wrote: “I SAID YES.”
Klum, who has three children from her marriage with singer Seal, went public with her relationship with Tokio Hotel guitarist Kaulitz in May.
They made their first public appearance together as a couple at a gala in Cannes.
She is a global star of the runway and was the first German model to be a Victoria’s Secret angel.
She has also appeared on Germany’s Next Top Model and Project Runway.
Klum married British singersongwriter Seal in 2005 in Mexico.
They announced their separation in 2012 and divorced in October 2014.
