Snooki has defended her 50 lbs weight loss.

The former 'Jersey Shore' star - who has an 11-month-old son Lorenzo with her fiancé Jionni LaValle - insists she did not do anything drastic to get her pre-pregnancy figure back.

The 25-year-old reformed party girl, whose real name is Nicole Polizzi, told People.com: "I work out in the gym seven days a week. I go with my trainer five days a week, I have a treadmill downstairs or I do crunches. I try to do something at least once a day.

"It's a part of my life - being fit is [a priority]. First was partying, now it's my son and working out."

Snooki says that no matter how busy she is she always makes time to exercise.

She said: "As long as you're motivated and dedicated, it's not hard at all."

The petite star credits her son for helping her adopt a healthier lifestyle but also believes he has made her become a nicer person.

She explained: "It's made me a better person, it's made me realise what life is really about and screw the bullsh**.

"I love my baby. He's my best friend. I love just laying in our playroom and he just crawls on me and we cuddle and giggle. That's like the best thing ever."
