Julia Roberts: ''By Hollywood Standards...I've Already Taken a Big Risk in Not Having a Face Lift''

Mother of three attributed her youthful appearance to natural anti-aging techniques such as "studying yoga on a more conscious level"

Unlike many Hollywood starlets, Julia Roberts has never gone under the knife—a decision which she claims was risky for her career. 

"By Hollywood standards, I guess I've already taken a big risk in not having had a face-lift," the 47-year-old stunner, who just happens to be celebrating her birthday today, said in an interview with You magazine (via the U.K.'s Telegraph) while speaking about her partnership with beauty brand Lancome. 

Roberts' comments come on the heels of rampant tabloid reports criticizing Renée Zellweger's new look, following her rare red carpet appearance at the 2014 Elle Women in Hollywood party last week. 

After the actress faced endless backlash with many claiming that she appeared ''unrecognizable,'' the 45-year-old Bridget Jones star addressed the speculation surrounding her makeover. "I'm glad folks think I look different! I'm living a different, happy, more fulfilling life, and I'm thrilled that perhaps it shows," she told People. 

Likewise, Roberts attributed her ageless beauty to all natural techinques, such as "studying yoga on a more conscious level" in order to maintain her youthful glow. 

And the Pretty Woman stunner—who has three children, twins Hazel and Phinnaeus, 9, and Henry, 7, with husband Daniel Moder—refuses to perpetuate the unrealistic Hollywood beauty standards. "I've told Lancome that I want to be an aging model–so they have to keep me for at least five more years until I'm over 50," she said. 

The Oscar winner, who has managed to live a low key life relatively out of the spotlight, despite having recently appeared in critically-acclaimed films such as August: Osage County, also attributes her enviable appearance to the peace she has found in her personal life. 

"It's about non-grasping, non-hoarding, cleaning out your closet, dusting out your mind and letting go of the things that weigh you down mentally and emotionally," she explained of her path to contentment. "There's a lightness to my life now — an airy quality of not taking things too seriously. That's happiness"
