The former 'The Hills' star was rushed to hospital after her car was struck by another vehicle while she was driving in Chicago.

It's been a difficult few months for the 29-year-old, whose brother Michael was found dead in Utah last December, and mother-of-three Kristin is said to be incredibly rattled by the latest incident in her life.

A source said: "After everything that has happened lately, the accident really shook her up. She's just thankful that she didn't get hurt."

Kristin is believed to "doing fine" after the crash, and will be discharged from hospital shortly, the source told People.com.

Her husband, sports star Jay Cutler, showed up at the hospital to be with his wife shortly after the crash.

None of Kristin's three children were present at the time of the incident.

Kristin has been keeping a low profile since the passing of her brother, who had been missing for a fortnight before his body was discovered.

Following the tragic loss, Kristin said she was seeking solace in her children, and her newborn daughter Saylor.

She wrote on Instagram: "My little angel, Saylor. She has been my light throughout this whole thing and has given me so much strength. Thank you baby girl for coming when u did."

Kristin and Jay - who also have sons Camden, three, and Jaxon, 17 months, together - welcomed Saylor in November.
