The glamour model and actress, who has been in a relationship with rugby player Thom Evans for about a year, said that she used to think the hobby was "cute" but now she just finds it irritating.
Brook told The Sun: "He used to be in a boyband so he is always singing something. At first I thought it was cute but these are the things that tend to annoy you in the end."
The couple tragically lost their unborn child earlier this year, five months into her pregnancy. At the time, she said that she experienced "moments of total sadness and devastation".
During and after her pregnancy, Brook praised Evans for being a great support and helping her be "very grown up" about the situation.
She has since insisted that she is still keen to start a family, saying: "Sometime in the next couple of years, I'd love to have children. But until then, I need to concentrate on the serious business of looking glamorous."
