Bar Refaeli is expecting a second child with her husband Adi Ezra

Alongside the photo, she wrote: "Something's cooking ... (sic)"

The Israeli model only gave birth to her daughter Liv seven months ago. The little one was born healthy, weighing in at 7lbs at Ichilov Hospital in Tel Aviv, Israel, on August 18, 2016. The couple's first child was born less than a year after they married last September.

Bar announced she was expecting on her Instagram account on New Year's Eve in 2015, by posting a picture of a baby and a bottle emoji on Twitter alongside a positive pregnancy test.

She accompanied the shot with the caption: "2016 is going to be like.. Happy & Healthy New Year ! (sic)"

During her third trimester with Liv, the stunner was still suffering from cravings as she posted a picture of a burger and added the caption: "officially pregnant #cravings. (sic)"

Last March, the star confirmed she was expecting a girl by uploading a photograph of her tiny baby bump whilst on a sun lounger.

She wrote: "My girl craved some vitamin D #5months (sic)."

Bar's pregnancy didn't come as much of a surprise to her fans as she has previously admitted a desire to have kids.

She said: "I would love to have kids soon. We keep feeling like we need some more time to ourselves but I think that feeling will never go away. So we will probably aim for children soon, I hope. I don't think marriage should [change a relationship].

"I believe people choose to get married because they are happy with their lives together, so why would we change anything? I didn't expect it - I always thought it would be the same as the day before the marriage - but you feel a spark of extra commitment when you call someone your 'husband.'"
