Those cheeks! Kristin Cavallari shares FIRST snap of baby Saylor

It's been an extremely difficult few weeks for reality star Kristin Cavallari, but there have still been some moments of lightness.

The mum-of-three took to Instagram yesterday to share a first proper snap of her new daughter Saylor with fans, a little over a month after her brother's tragic death.

"Here is my angel Saylor. I couldn’t have asked for a better baby," she told fans via her app.

"We’re very lucky to have such a sweet, easy girl, especially since she’s the third one!"

Kristen and her husband Jay Cutler already have two sons together, three-year-old Camden and 19-month-old Jaxon.

Last week Kristen admitted it had been a difficult road learning to cope with the loss of her older brother Michael. The 30-year-old's body was found in a mountainous area close to where his abandoned car was located in Grand County, Utah.

It's believed that prolonged exposure to the elements lead to his death.

Taking to Instagram on Jan 2, Kristen said she was taking small steps to get back to normality.

"Last night was the second time I've put makeup on in over 5 weeks and left the house (besides the grocery store and taking Cam to school)," she wrote alongside a snap of herself and her husband enjoying a glass of wine.

"Even though I shed a few tears, it was a really nice night and felt good to be out."
