“HAPPY #mothersday to all the Moms around the World 😘,” Klum captioned the hilariousclip.

Klum is also mom to daughter Lou, 9, and sons Johan, 12, and Henry, 13.

Klum will celebrate Mother’s Day on Sunday with her fiancéTom Kaulitzfor the first time since the couple got engaged.

When Kaulitz proposed to her on Christmas Eve 2018, he made sure to get the blessing from all four of the supermodel’s children.

“They went to Mexico before their engagement, around Thanksgiving, and that’s when he started talking to the kids about his plans in secret and it was so hard for them to not tell anyone. They were so excited and happy for their mom,”a friend of Klum told PEOPLEat the time.

One month later, on Christmas Eve morning, “Tom went to the kids and asked for Heidi’s hand in marriage and they said ‘yes,’ ” the friend shared

“So Tom and the kids together worked on making a breakfast tray for Heidi that had coffee, flowers, and a ring box,” the friend continued. “It was important for Tom to have the kids included in the whole thing, so they all brought the tray up to Heidi’s room and surprised her with breakfast in bed and then he proposed.”

The breakfast-in-bed proposal couldn’t have been any more perfect for the supermodel.

“She loved his thoughtfulness and that he included the kids,” the friend added. “They all surprised her together and she loved how he made the kids feel a part of it.”
