Nope, that's definitely not an engagement ring on her hand!
No, that is definitely not an engagement ring on Heidi Klum's finger at the 2015 Emmys Red Carpet.
"This is just a beautiful bauble from Lorraine Schwartz," the 42-year-old model told ET's Kevin Frazier on Sunday, flashing a stunning gold sparkler on her left hand.

"I won't get married again," Klum said decisively, shutting down rumors that she and boyfriend Vito Schnabel, 29, could be headed down the aisle. "People always write all these crazy things, but it's not all true. Don't always believe what you read in the paper!"
Still, Klum couldn't help gushing over her art curator beau, confessing that she's "very much in love."

Klum also opened up about Donald Trump's surprising dig at her last month, when he declared that the America's Got Talent judge is "no longer a 10." Klum, of course, fired back in a hilarious video on social media.
"I thought it was actually a lot of fun, to be honest with you, in a strange way," she told ET of the diss. "I loved having fun creating that video and, you know what? Two days ago, I saw Bill Clinton and he thought that was such a fun video that I posted -- and coming from Bill Clinton, that made me very, very happy that I was even on his radar. Who knew?!"
Of course, that's just one of the many reasons we love Heidi! She's always a class act. See her wishing her ex-husband, Seal, well in another recent interview with ET, below.
