Saying that Indian bookmakers were using the Bollywood actress as a honey trap to fix international matches and also England county games, the Times claimed that it had evidence that tens of thousands of pounds were offered to players for spot-fixing.
Even though the Times did not name her, an image with a blurred face was published in the newspaper that resembled Mehta, media reports said.
Nupur, who has worked in Sunny Deol-starrer Jo Bole So Nihal (2005), on Monday said that she had been accused o something she had not done.
"All I would say is I am not guilty of any such thing. The picture that they have used was taken during my film Jo Bole So Nihal," she was quoted as saying.
"I intend to take action against them," she added.
Meanwhile the International Cricket Council (ICC) also dismissed The Sunday Times' claim that it is investigating the Cricket World Cup 2011 semi-final match between India and Pakistan.
In a statement, the ICC Chief Executive Haroon Lorgat said: "The story carried by the newspaper, in which it has claimed that the ICC is investigating the ICC Cricket World Cup 2011 semi-final between India and Pakistan, is baseless and misleading. The ICC has no reason or evidence to require an investigation into this match."
"It is indeed sad for spurious claims to be made which only serve to cause doubt on the semi-final of one of the most successful ICC Cricket World Cups ever," he said.
