Heidi Klum shares steamy post with husband on anniversary

Heidi Klum and Tom Kaulitz are celebrating four years of marriage with a sweet video and kissable picture as a treat.

In the caption of an Instagram photo on Wednesday, the supermodel, 49, referred to the musician, 33, as the "love of my life" while they were celebrating their wedding anniversary.

Klum posted a video of her and Kaulitz kissing in bed at the start of the carousel. She also listed notable features of their house, which had been specially decorated with a sizable arrangement of long-stemmed roses and a variety of red heart-shaped balloons.

She also posted a photo of two colourful cakes up close, one of which had "4 years" inscribed in brown frosting.

The pair wed in a private ceremony in February 2019, and in August 2019, they celebrated lavishly with loved ones and close friends in Capri, Italy.

Heidi Klum and Tom Kaulitz relationship altogether:

The couple announced their engagement on December 24, 2018, after Kaulitz proposed to Klum over breakfast in bed in front of her children, boys Johan, 16, and Henry, 17, whom she shares with her ex-husband Seal, as well as daughters Lou, 13, and Leni, 18.

"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 People magazine at the time.

On Christmas Eve, "Tom went to the kids and asked for Heidi's hand in marriage and they said 'yes,' " the friend added.

The source added: "He plays sports with Heidi's boys and is involved in activities that the girls enjoy. Heidi loves his energy and take on life and feels very grateful that she met Tom."
