Hailey Bieber has slammed speculation she has had plastic surgery.

The 23-year-old model didn't hold back as she responded to an Instagram post reportedly comparing a photo of her as a teenager to one from the present day and insisted the newer snap wasn't an accurate reflection of her looks.

She commented: ''Stop using pics that are edited by makeup artists!

''This photo on the right is NOT what I look like... I've never touched my face so If you're gonna sit around and compare me at 13, and then me at 23, at least use a natural photo that wasn't edited so crazy. (sic)''

Her response comes after she recently admitted scrutiny of her marriage to Justin Bieber, 25, has made her feel like ''less of a woman''.

Hailey - who married the 'Yummy' hitmaker in 2018 - insisted it's ''not easy'' to deal with the criticism they have received, especially when people draw ''comparisons'' between herself and Justin's former partners - most notably singer Selena Gomez.

The loved up couple were answering fan questions on their Facebook Watch show 'The Biebers on Watch' when one asked how they ''manage to be a couple when everyone feels like they have a say in their relationship.''

And the blonde beauty said: ''It is definitely not easy. Justin knows I have a hard time with the things people say and the ways people make comparisons ... The way they have made me feel like less of a woman.''

The model said she always tries to be the better person when things get too much, as she knows the trolls who slam her are probably ''going through something bad'' themselves.

She added: ''I think when people have a lot to say or go out of there way to make people feel less than it is because they are going through something bad. It helps to remind myself that that person is going through something themselves.''
