Hilary Duff has posted a confrontation with a paparazzo to her Instagram account along with a strong message: "this is not okay."
The singer and actress filmed a man who she says had been "stalking her like pray for hours" where she can be heard pleading with the photographer.
"I've asked you once to leave me alone, can you please stop taking my picture?" she asks in the video.
"You're like, hunting me down."
Duff goes on to tell the man she is "nine months pregnant," and feels "very uncomfortable" with the situation.
The former Lizzie McGuire star told her 10 million Instagram followers she had been followed at her son's soccer game, during a visit to her sister's house and while running errands.
Rather than apologising, the paparazzo responds that he "didn't get any photos" and has "lost his whole morning" chasing her around.
"When people say that's what you get for signing up to be a celebrity it honestly makes me sick," she captioned the video.
"This is every day of every month and it's simply not ok.
"If a non-'celeb' (I'm sorry to use that word) was dealing with this, the law would be involved."
The clip, which shows the photographer's face un-censored, has been viewed almost two million times.
