It looks like Christina Aguilera is the latest celebrity to deny plastic surgery rumors following her 35-pound weight loss.

According to Hollywood Life, the 33-year-old is denying reports that she has had liposuction after new claims allege that her slender body was achieved through surgery rather than diet and exercise.

A source close to "The Voice" judge told Life & Style magazine, "Christina didn't get lipo. She's worked hard to change her eating habits, and you can see the results."

The insider revealed, "The last thing Christina wants to hear is that people are talking about her losing weight with liposuction. She's sick and tired of people assuming things about her body."

The source said, "Christina takes her lunches and snacks with her to work now, so she can watch how much she eats instead of overindulging in anything bad for her."

The talented singer has since cut back on alcohol, limiting her intake of empty calories but occasionally treats herself to a glass of wine. A friend of the mother of one admitted, "She eats carbs, protein, snacks like pretzels - she just watches how much she eats."

Nutritionist Keri Glassman explained, "If you learn to control portions and also focus on eating the right quality foods - those loaded with fiber and protein - you'll end up being healthier and lose weight.

"It's important not to eat until you're stuffed and also not to wait until you're starving."

In an effort to burn calories and relieve stress Christina Aguilera does yoga.

An insider confessed, "She loves her body now. She really is happy."

In the past the singer has said, "Whatever size or shape you have, it's important to embrace it."
