Myleene Klass is stepping up security at her home
TV presenter Myleene Klass has said she has "no regrets" after being warned by police for waving a knife at youths who entered her back garden.
The former pop star was in the kitchen when she spotted the teenagers and grabbed a knife and banged the windows in an effort to get them to leave.
She says Hertfordshire Police officers told her that brandishing an "offensive weapon" was illegal.
But a police spokeswoman said that "at no point" were any warnings given.
The 31-year-old was at her Potters Bar home on Friday with her daughter upstairs when she spotted the youths peering into the house.
Klass said: "It was a scary incident but I've got no regrets as to how I reacted. I think I did what any other mother would do.
"This is my house and that's my daughter up there and I will do anything to protect my daughter and my family. That's what I did."
The star was speaking at the launch of new ITV1 series Popstar To Operastar - which features former chart stars as they try to make it as classical singers.
Klass's spokesman, Jonathan Shalit, told the Sunday Telegraph the singer had been "utterly terrified" and was stepping up security at her home.
"Myleene was aghast when she was told that the law did not allow her to defend herself at home," he said.
"All she did was scream loudly and wave the knife to try and frighten them off.
"She is not looking to be a vigilante, and has the utmost respect for the law, but when the police explained to her that even if you're at home alone and you have an intruder, you are not allowed to protect yourself, she was bemused."
But a statement from Hertfordshire police said: "Officers spoke to reassure the home owner, talked through security and gave advice in relation to the importance of reporting suspicious activity immediately to allow officers to act appropriately."
It added: "For clarification, at no point were any official warnings or words of advice given to the home owner in relation to the use of a knife or offensive weapon in their home."
Mr Shalit could not immediately be reached for further comment.
Klass's fiance Graham Quinn was away on business at the time of the scare, but the couple's daughter was upstairs at the time the intruders were spotted.
