Heidi Klum and Tom Kaulitz

Heidi Klum made her red carpet debut as an engaged lady at the Golden Globes. The America’s Got Talent judge, who said, "yes," to Tom Kaulitz last month stepped out with a stunner of an engagement ring as special and unique as the former model herself. Her fiancé proposed to the German beauty with a gorgeous three-stone ring that featured a green center gemstone surrounded by a halo. The non-conventional design was further accented by two cushion-cut diamonds on each side in a white gold or platinum setting.

Based on the center stone’s slightly bluish hue, Heidi opted for what appeared to be a teal sapphire. It’s also estimated that the stone is a 3-5 carat elongated cushion or emerald-cut stone, and depending on the quality could have cost a whopping $20,000 to $30,000.

The mom-of-four announced the joyous news of her engagement on Instagram during Christmas Eve. The engagement came a little over a year after the lovebirds started dating. Heidi shared a black and white photo where she’s seen peeking behind her smiling fiancé and her left hand drapes over his face. In a caption, she wrote, “I SAID YES,” followed by a red heart emoji.

Back in September, rumors about the handsome pair being engaged swirled as they appeared cuddled up at the Emmy Awards’ carpet. Most intriguingly, Heidi was wearing an enormous sparkling diamond ring on her engagement finger – which she made zero attempts to hide as she posed for pictures with her 29-year-old musician love who was a guitarist in the band Tokio Hotel.

However, when asked about the dazzling rock Heidi was quick to put the rumors to rest. “No, all these are just borrowed,” the 45-year-old told ET's Nancy O'Dell. “They go with that necklace beautifully… Don’t read into anything. They just pretty rings," she said.

Following the rumors, Heidi and her beau traveled to Mexico, with her kids and Tom’s twin brother, where she documented some lasting memories for her Instagram followers. There’s no given date as to when or where their nuptials will take place, but all signs point to sooner rather than later.
