Renee Zellweger doesn't look the same anymore, and it's not because she has lost or gained weight for the popular Bridget Jones' series.

The American actress turned up at ELLE Women In Hollywood Awards in Los Angeles on Monday with tighter skin and eyes that look very different.

In fact, according to Britain's Metro, Zellweger was nearly mistaken for Cameron Diaz at the event. Some even say she looks like American actress Robin Wright Penn.

The drastic change prompted speculation of plastic surgery even though she has never admitted to going under the knife.

According to plastic and cosmetic surgeon Alex Karidis of London’s Karaidis Clinic, in an interview with MailOnline, the smaller distance between the brow and her eye might be caused by an upper eye lift.

However, another expert, Dr Yannis Alexandrides, claims that Zellweger may have undergone a non-surgical treatment called Thermage instead - a procedure that "uses radio frequency to tighten elastin fibres and stimulate collagen and gradually improves the quality of the skin and tissue over a period of six months".

Fans, too, were not exactly sure what happened:

Plastic surgery or not, it will definitely take some time to get used to the new look.
