My Worst Week (BBC1): CELEBRITIES who sin know that their moment of wrongdoing will be repeated more often than an old Carry On comedy.

Forgive and forget isn't a concept that appeals to the makers of this trashy, but unashamedly watchable, series which put Hugh Grant back in the dock this week.

The question the programme didn't answer was the one that fascinated us all at the time he was "blown away by his relationship with a 60 dollar hooker". Why would a successful actor in a long-term relationship with one of the most beautiful women in the world risk his reputation by performing a sexual act in a car with a prostitute? "Why did he do this?" asked presenter Iain Lee before failing to supply an answer. Getting arrested seems an extreme way of publicising your new film, as Grant was supposed to be doing at the time.

The scoop for My Worst Week was getting Hollywood hooker Divine Brown to tell us everything that the BBC rules of decency allowed about her close encounter with the actor. The makers even helpfully reconstructed events, or as much as possible without becoming a porn movie.

Apparently, what gave Grant away to the cops were the flashing lights on his car as his foot hit the brakes as Divine applied herself to the job in hand. If only he'd agreed to pay an extra 40 dollars for a hotel room. "Basically he was tight and paid the price," said one observer.

Ms Brown is clearly no cinemagoer as she didn't recognise her famous client, who was charged with committing a lewd act in a public place. She also didn't realise that she was a wanted woman - wanted by the world's tabloid press. Sunset Boulevard was swarming with cheque book journalists looking for her.

One had 10,000 dollars stuffed down his underpants for safe keeping, although wouldn't that be the first place a prostitute would look? "That was just a down payment," he explained. "She was worth a lot more than that, but I couldn't fit any more down my underpants."

Those unfamiliar with how Fleet Street operates would have been fascinated by the extraordinary lengths reporters went to sign up Divine and then ensure no one else spoke to her. She was kept captive in a hotel room until her revelations appeared the following Sunday. The witness protection programme wouldn't have given her such five-star treatment.

Grant, meanwhile, embarked on a damage limitation exercise as he resumed his promotional duties in America, after letting the British press photograph him with Ms Hurley. The strategy worked. It caused him embarrassment for a few months, but had no lasting detrimental effect on his career.

Divine seems to have learnt nothing from the experience. She earned a million dollars from the episode and is now back on the streets.
