Heidi Klum and her boyfriend are definitely making their relationship work.

The 39-year-old Project Runway star and her 45-year-old bodyguard boyfriend, Martin Kirsten, have exchanged matching diamond bands, according to Life & Style.

The couple were recently spotted wearing matching Tiffany & Co. Etoile gold-and-diamond bands on their right ring fingers. So cute!

And what was the occasion for them to get the rings? 

“It’s a present from my boyfriend,” Heidi reveals.

It sounds like things between Heidi and Martin are going stronger than ever, which is awesome news! Might an engagement ring be on the way? We wouldn't be shocked.

Heidi and Seal split up last year after their seven-year marriage, and Heidi confirmed her relationship with Martin in September 2012.

Heidi has even recently said, “Yes, I’m in love!”

She can be seen joining the judges' table on America's Got Talent this summer.

Will we get to catch a glimpse of her blinged-out Tiffany ring on that show? Let's hope so!
