The 46-year-old "Bridget Jones's Diary" star hit headlines and became a trending topic on Twitter after she made her first public appearance in months at an awards show in Los Angeles in October, 2014, sparking a debate over her 'new face', reported People magazine.
Zellweger shrugged off the media storm at the time, putting her altered appearance down to a new, relaxed lifestyle, and now she reveals she didn't even know about any of the comments because she does not participate in any kind of social media.
Zellweger previously defended her image and insisted she looks different because she is much happier in life.
The actress returns to the Bridget Jones franchise for third film "Bridget Jones's Baby" later this year.
