British model and actress Liz Hurley has rebuffed rumours that she was planning to marry her boyfriend, the Indian millionaire businessman Arun Nayar.

Reports that she was going to get married to Nayar in February were a "myth", said Hurley.

"We are absolutely not getting married. It's a complete and utter myth", said Hurley.

She also poured scorn on rumours that her former lover, actor Hugh Grant, would tie the knot with Jemima Khan, the ex-wife of the Pakistani politician and former cricketer Imran Khan.

Hurley, 40, who dated Grant for 13 years before they split up in 2000, said the actor and Khan had no plans to marry.

"I don't see him as much these days, but I do know that he's not getting married, even though that has been written about in the newspapers", she told Grazia magazine.

"I think I would know if he was and I do know that he isn't."

Hurley and Khan, the 31-year-old heiress daughter of the late millionaire Sir James Goldsmith, are known to have frosty relations.

Grant's continued feelings for Hurley have been blamed for undermining his 18-month relationship with Khan, who has two sons with her former husband.

She said: "He's a big part of my life and it hasn't been a problem with Arun. Hugh is my best friend and I can't imagine life without him."
