American reality TV star Beth Chapman, the wife of US star Dog the Bounty Hunter, has hit out on Twitter after she was forced to pull out of Celebrity Big Brother.

The 49-year-old blonde was billed as one of the American stars entering the house, but a tabloid reported she had to drop out at the last minute.

Reports suggested the fifth wife of Dog, real name Duane Chapman, had allegedly been denied a visa to enter the United Kingdom.

Beth hit back on Twitter, replying to fans:

She posted a photograph of herself in her home and hinted at the identity of two of the other rumoured American housemates by wishing them both good luck.

Her post refers to Mob Wives star Renee Graziano and Danity Kane singer Aubrey O’Day.
