London, Aug 11 - Jennifer Lopez, who is struggling to get into shape post pregnancy, has refused to go under knife for the perfect figure. The singer-actress says she is a 'more natural' person.

Lopez gave birth to twins Max and Emme in February 2008 and gained around 60 pounds during her pregnancy, reports femalefirst.co.uk.

'I thought the weight was going to drop off easily because I had been in shape my whole life. But it wasn't easy. It was an uphill struggle I had gained about 60 pounds during pregnancy,' said Lopez.

'I don't see myself having any plastic surgery. I don't know how I will feel when I am older. But I am more of a natural person and I believe in beauty not being an outside, physical thing. Luckily, I'm used to seeing myself everywhere now that I am no longer obsessed about the way I look,' she added.

'I have to say I feel awesome! I feel the same way I felt when I was in my 20s,' said the 40-year-old who is married to Marc Anthony.
