Los Angeles, Nov 28 (IANS): Hollywood star Jennifer Lawrence's appearance has shifted because she's "ageing" and not because of plastic surgery, says the actress.

The 33-year-old actress agrees that her appearance has changed over recent years, but she says she hasn't gone under the knife.

"I started at 19, so I get the before and after pictures from when I'm 19 to 30 and I'm like, 'I grew up. I lost baby weight in my face, and my face changed because I'm ageing.' Everybody thought I had a nose job, and I'm like, 'I've had the exact same nose. My cheeks got smaller. Thank you for bringing it up,' " Lawrence told Interview magazine.

She highlighted the influence of Hung Vanngo, the acclaimed make-up artist, reports aceshowbiz.com.

She explained, "I also think it's incredible what make-up can do because I work with Hung, who overlines the lip, and I call him a plastic surgeon because everybody in the last few months, since I've been working with him, is convinced that I had eye surgery."

Meanwhile, Lawrence previously revealed that she struggles with mom guilt.

The award-winning actress confessed that she was still trying to come to terms with the demands of motherhood.
