Heidi Klum shares revealing kissing selfie on fourth anniversary with husband: ‘Love of my life’

The supermodel and her 'Tokio Hotel' husband were married on Feb. 22, 2019

Heidi Klum shared a revealing selfie of her martial bliss with musician husband Tom Kaulitz with what appeared to be them kissing in their underwear – although it was hard to tell if they were wearing anything – for their fourth anniversary Wednesday. 

"Love of my life," she captioned the Instagram post with a heart emoji. 

In the photo, dozens of red heart-shaped balloons covered the ceiling of their home. 

The supermodel and "America’s Got Talent" judge also shared two other photos and a short video of the couple kissing and nuzzling.

Another photo showed two cakes, including a sprinkle-filled one that said "4 years" and the last photo was a closeup of a bouquet of roses and the ceiling-clinging heart-shaped balloons.

Earlier this month, Klum, 49, told Jennifer Hudson on her talk show that it "depends on what day it is" on whether she’d like to have a baby with Kaulitz, 33. 

The model shares four children with ex-husband Seal.
