GWEN Stefani has shocked her fans plenty of times with her forever-changing and youthful looks.
But according to a plastic surgeon, the Grammy Award winner is not the only celeb on The Voice who has spent thousands "manipulating" her face.
The Voice coach Reba McEntire, 68, celebrated 100 million streams of her song Fancy two weeks after joining the music show panel.
Alongside John Legend, 44, and Niall Horan, 30, Gwen, 54, shared the news on Instagram.
Fans commented on her looks and seemed shocked by the mother of three's appearance.
Remarking on the October 10 post, one wrote: "Congrats Ms. Reba but who the heck is that talking? That is not Gwen Stefani."
Advertisement insisted Reba looks "full in the face" on the hit NBC show.
In an exclusive interview, Westreich told The U.S. Sun: "It is Reba who has started to look puffy in her face.
"For Reba, I would say do not get any fuller in her face.
"Over the years she may have had a rhinoplasty, brow lift, and upper lid lift, as well as a facelift and fat transfer."
Westreich claimed Gwen has been maintaining her "love affair" with lip filler.
He previously told The U.S. Sun how Gwen's pricy tweakments involved her "messing with her lips" from 2014 onwards.
"I would advise Gwen not to do so much filler anymore because her lip rolls out now," he said.
"The upper lip is rolling when she smiles and it is starting to look lumpy.
