Charlotte Church becomes 'depressed' about the constant press pursuit over her private life, according to her mother.
The media's gaze has sharpened on Church over her new relationship
Press photographers, or paparazzi, are a particular problem, said Maria Church, because they follow her "morning, noon and night".
Mrs Church told the BBC the problem had become worse since her daughter, 19, began dating rugby star Gavin Henson.
She also said the the singer has only one to two friends she can trust.
Speaking to BBC Radio 5 Live, Mrs Church, who runs a pub in the family's home city of Cardiff, railed against the treatment of her daughter by some parts of the media.
She said: "If she's out and about in town or the centre of London it can be very, very aggressive.
"I've been with Charlotte when we've been pushed, stamped on, anything to get that photo.
"I have no respect for them whatsoever... She's a bit better about it now, but about a month ago it was really getting her down and really making her depressed.
The former child star has few friends she can trust, says her mum
"It really has got Charlotte down and she's become quite depressed sometimes."
In March, Mrs Church admitted she was "over the moon" to learn her daughter was dating Henson, who plays for the Swansea-Neath Ospreys.
She said her advice about her previous boyfriends had fallen on deaf ears.
Church had lived with model Steven Johnson and also went out with trainee chef Kyle Johnson, also 19, who then sold a kiss-and-tell story to the tabloids.
Mrs Church said: "She wouldn't listen, I knew it was going to happen.
Mrs Church says she always told her daughter to go out with a celebrity - like Henson - as she believed they would be les likely to sell a kiss-and-tell story.
But, she went on to say that in some ways her relationship with the rugby star has only fuelled the media's interest.
