Louise Redknapp's appearance on Good Morning Britain today promoted some fans to beg her to take it easy on the botox.
The stunning singer was chatting about her upcoming album, but some viewers found themselves distracted by how different Louise, 45, looked.
Known for being an ageless beauty, mum-of-two Louise has not spoken openly about whether or not she uses fillers or anti-wrinkle injections.
But fans took to Twitter to wonder at her drastically different appearance, with some urging her not to take things too far and branding her "puffy".
"Has Louise Redknapp has work done? She looks very puffy in the face," wrote one.
"Has Louise Redknapp had work done to her face? Can't put my finger on it but she looks so different ... not knocking it, if it makes her feel good like, all about empowerment!" added another.
"What has @LouiseRedknapp done to her face ? She’s beautiful anyway don’t spoil your good looks girl @GMB #fillers #botox #loveyourself " urged a third.
A fourth added: " @LouiseRedknapp what on earth has happened to you? On morning telly today you dont even look like you. Is it botox? Please stop."
MirrorOnline has reached out to a rep for Louise for comment.
Louise, who starred in Strictly Come Dancing in 2016, was chatting about her upcoming album, Heavy Love, with hosts Susanna Reid and Ben Shephard.
She revealed she was "heartbroken" over her ex husband, footballer Jamie Redknapp, while she wrote the songs.
Louise said: "I wrote this album over a two-year period. It’s a very personal album.
"I never thought I’d do music again, so being here in the position where I’ve just released an album after 20 years… not only does it mean the world and I’ve kind of bared my heart and soul a little bit on this album… you don’t want to fail.”
She added: "I was so fortunate to have success twenty years ago with everything that you just want to keep the momentum going and you kind of want to do what you love. You need to sell records to do what you love, so yeah, I’m nervous, but excited as well.
