KRISTIN CAVALLARI still has the first pair of Christian Louboutin heels she bought when she was a teenager.

The 27-year-old former 'Hills' star - who is expecting her second child with husband Jay Cutler - cherishes her first pair of the designer's shoes as they bring back happy memories for her.

She said: ''The oldest thing in my closet is the first pair of Louboutins that I bought when I was 18. I remember being so excited. They are simple, black open toe pumps.''

While she's nostalgic for some things she had as a teenager, blonde Kristin - who is already mother to son Camden, 19 months - would rather forget the time she dyed her hair dark.

She added to Life and Style magazine: ''A moment I'd like to forget is when I dyed my hair black in high school. It looked awful and ruined my hair. I had to strip my hair and then have it dark brown and slowly work my way back to blonde.''

When it comes to style, the fashion designer looks to British model Kate Moss for inspiration because ''she always looks so effortless and chic.''
