Heidi Klum and Tom Kaulitz are getting married.

The model confirmed the news on Instagram and Twitter, sharing a black-and-white photo of herself with her beau. In the portrait, she showed off her new engagement ring.

"I SAID YES," Klum wrote.

The 45-year-old is said to be over the moon. A source recently told People she is "so in love" with Kaulitz.

News of their engagement comes just three months after Klum shut down rumors Kaulitz popped the question. Those rumors surfaced after Klum was seen wearing a massive diamond ring on her left ring finger at the Emmy Awards.

"I don't know why everyone keeps saying that. Everyone is asking me. When you do what I do, you wear a lot of fashion. A lot of jewelry. I always look for something that goes with the outfit. So, I wear big rings," she said at the time.

She added, "there is nothing more to it than that."

Rumors first began swirling about Klum and Kaulitz, 29, dating back in March. The couple was seen kissing on the America's Got Talent set. They didn't make their first public appearance as a couple until months later, at the amfAR Gala in May.
