Hudson denies rumours that she had problems with Hathaway, her co-star from the romantic comedy Bride Wars.
According to Us Weekly, the two women, who played enemies on screen, had no problems transposing their hatred in front of the camera.
A source told the tabloid, "She (Hudson) was just awful to Anne…(but) she (Hathaway) never played into Kate’s cattiness."
A representative for Hudson, who is Goldie Hawn’s daughter, said of the rumours, "She and Anne have always been good girlfriends and remain good girlfriends. This is ridiculous and couldn’t be further from the truth."
