Gong Li and Colin Farrell in 'Miami Vice'.

The pair sparked reports they were enjoying a heady romance when they were spotted hand-in-hand at a plush post-premiere party in London - but Li is convinced the Irish lothario is just being sweet.

She says, "He treats everybody well and takes great interest in everyone around him - not just me, but the crew as well. As a result, it's easy to feel relaxed around him."

The MEMOIRS OF A GEISHA star, 40, also admits she has been taking the opportunity to "teach him how to drink mojitos", a strong cocktail of rum, lime and soda, on their nights out together.
