Mother-of-four Heidi Klum, 49, is open to having kids with third husband Tom Kaulitz, 33: 'It depends what day it is'

Heidi Klum recently revealed her thoughts on having another kid, with her current husband, Tom Kaulitz.

While appearing on Thursday's episode of the Jennifer Hudson Show, the Making the Cut star, 49, shared that she has considered expanding her family and having a baby with Tom, 33.

'It depends what day it is, sometimes I'm here [for it], sometimes here [where I am not], you know?' the German beauty said.

Heidi first became a mother in 2004 with the birth of her first daughter and went on to welcome three more children with ex-husband Seal.

'I mean it's a lot. I've done it four times. I breastfed eight months each time [with my four kids] and then I was pregnant again.'

She continued: 'Three times in a row. Again [my children are] 18, 17, 16, and then 13. Now I waited a long time, so maybe [yes].'

Tom, who is a musician in the band Tokio Hotel, is Heidi's third husband.

The guitarist was married once before to model Ria Sommerfeld from 2015-2018, but the pair had no children together.

Heidi had her first daughter, Leni, with Flavio Briatore, 72.

The America's Got Talent judge then went on to marry the musician Seal and have her other three kids with him. Seal adopted Leni in 2009.

The pair were married from 2005-2014 and co-parent their kids Henry, 17, Johan, 16, and Lou, 13.

In 2018, the star sparked romance rumors with Tom after they were spotted holding hands on multiple outings.

They got engaged later that year and secretly wed in February 2019.

In 2022 the star gushed to US Weekly about how quickly Tom blended with her family after getting married.

'[Tom's] amazing. I'm sure it's not easy to step into an immediate family, having all of a sudden four kids and teenagers.

'They were easier when they were younger, for sure. Every age comes with its challenges. … It's beautiful. It's fun. I mean, so far, so good.'

While on the Jennifer Hudson Show, Heidi also talked about her upcoming 50th birthday and how she expressed to her husband that a big bash is expected.

She gushed to Jennifer, 'I told my husband, you better get on it, it better be good.

'Because every year it wasn't a big birthday ... you'll always have family and friends, but I thought 50, that's like a pretty big number.'

Heidi continued, 'So I said to my husband, 'I would love to now have a big birthday party. Do you hear me, my love?''
