Kristin Cavallari has welcomed her third child.

Sharing a photograph of a pink onesie on her Instagram account, she captioned the image: "Saylor James Cutler was born today at 132pm!! (sic)"

The 28-year-old fashion designer also revealed the baby, which was born on November 23, weighed a healthy 7lbs 6oz.

Meanwhile, Kristin - who also has three-year-old son Camden and 17-month-old son Jaxon Wyatt with husband Jay Cutler - previously admitted the thought of raising her growing brood "kind of scares her".

She explained: "I'm not going to lie, three kids kind of scares me. I'm going to be alone with three children a lot, but we're just going to figure it out.

"[Camden is] really sweet, so I'm just hoping that he'll be my little helper and help me out as much as possible."

She also admitted she is looking forward to have a nursery where "everything is pink".

She shared: "Everyone's really excited. I'm already getting the nursery ready! I didn't think I would be a big 'pink' girl but everything is pink. There's a chandelier. I'm getting all the pink and purple clothes.

"I'm just excited to have a little mini me and now I have someone that I can give all of my stuff to, which is great."
