Heidi submitted paperwork for the name change last month in court, citing 'marriage' as the reason for the change.
Heidi decided it was time to make the change legally after four years of marriage and three children together. Heidi also has a daughter from a previous relationship.
There's no word on whether she'll adopt his name professionally too, but we're hoping she doesn't. While it's cute that she adopted her husband's last name, with a name like Heidi Klum, you're practically destined to be famous! Heidi Samuel, not so much.
Meanwhile, while at the Victoria's Secret show in New York, Heidi took time out of her busy schedule to talk to Hollyscoop exclusively about her holiday plans.
"For Thanksgiving, five days, I'm going to be home cooking up a big fat Turkey and sweet potatoes with the marshmallows on top," Heidi told Hollyscoop exclusively backstage at the Victoria's Secret show in New York.
"I do the graving, the stuffing and cranberry sauce. I love it! I wake up early, and paste that thing. It's fun!"
Sounds like Mr. and Mrs. Samuel have a fun filled Thanksgiving ahead of them!
