Alias beauty Jennifer Garner insists she slimmed down after childbirth by breastfeeding, because she had no intention of abandoning her daughter to hit the gym. Garner, who is married to Hollywood heartthrob Ben Affleck, gave birth to Violet in December last year and refused to put her child at risk by exhausting her body with an intense exercise regime. The 34-year-old says, "(I lost weight) breastfeeding! That and a moderate exercise and eating plan with the help of my personal trainer. I wasn't about to jump on the celebrity mum bandwagon of getting super-skinny, super-quickly. I am more concerned about keeping healthy and spending time with Violet than anything else."
