Kristin Cavallari's fiance tells her if she gets too thin.

The 26-year-old former reality TV star - who has eight-month-old son Camden with partner Jay Cutler - feels ''lucky'' that the NFL player never pressures her about losing weight, but she still takes care of her body.

She told the latest issue of Disfunkshion magazine: ''I'm lucky to have Jay who would rather have a couple pounds on me. He tells me when I'm too skinny. That helps.

''I take care of myself, go to the gym, eat well. There are good and bad days.''

Kristin and Jay, 29, love being parents and think raising Camden comes easier as they discussed their ''parenting philosophies'' before he was born,

She said: ''Having Jay is really helpful. It's important to talk about parenting philosophies before having a child. You want to go in knowing how to raise them to avoid the arguments that can ensue. Being good parents is our top priority.''

And the shoe designer - who lives in Illinois with her family - has even turned down work because it was disrupt life with her son.

She said: ''Being a mom has definitely changed my priorities. It's all about him. I've turned down jobs that would have kept me in L.A. because I want to be there for him.''
