However, when he was seen at her new bar, M2, in Shanghai recently - and her actor boyfriend Tony Leung Chiu Wai wasn't - tongues began to wag again, reported Sing Tao Daily.

Last Friday, Lau, 41, laid the new rumours to rest by revealing that she and Leung, 45, visited the Karmapa Lama in India together recently.

She said it was their first visit, and that a friend had introduced them to the Tibetan religious leader. 'I hope the Karmapa can pass on some wisdom to me because there are many things I don't know,' she said at a fashion show.

Leung has been busy filming director John Woo's history epic Red Cliff in Beijing, and she said she would not visit him.

'I seldom visit Wai Chai on set because I don't want to get in the way of his work and affect his performance. He wouldn't know whether to pay attention to me or his work,' she said, calling Leung by his nickname.
