Kristin Cavallari feels 'too thin'

Los Angeles: Reality TV star Kristin Cavallari is trying to gain weight as she is worried she looks too skinny.

The former “The Hills” star has revealed she is trying to bulk up after giving birth to her sons, Camden, two, and eight-month-old Jaxon, with her husband Jay Cutler, as she doesn't like looking too skinny.

"I don't know why or how but after I had children my body literally changed and now, for me, it's about trying to keep muscle on so I don't look too thin,” femalefirst.co.uk quoted Cavallari as saying.

"Because it's very easy, especially because I have no curves, that I can look really skinny and I don't like that look,” she added
