Sienna Miller has reportedly been given a new hairstyle by computer artists for her new film Hippie Hippie Shake - and we’re not talking about the hair on her head.

Sienna plays the hippy girlfriend of controversial publisher Richard Neville in the period piece and has to get naked on a number of occasions, and that’s where, according to the Mirror, problems occurred.

A source told the newspaper: “The film is set in the swinging ’60s when fashion was wild and body hair even wilder.

“Sienna was an absolute star throughout filming and her performance was flawless. The only slight problem being that she’s very much a girl of the Noughties - and this extends to her personal upkeep.

“Unfortunately, Brazilians weren’t common in the ’60s and Sienna’s part involved nude scenes - meaning that her grooming habits were on full display.

“A merkin or pubic wig simply wouldn’t have done the trick, but luckily computer wizardry came to the rescue. Sienna’s private parts were digitally enhanced, giving her a rather unruly, loud and proud bush.

“All the cast had a good giggle about it and stoical Sienna happily played along. But it’s safe to say this is one look she won’t be recreating on her next summer hols.”

The film, which also star her Edge of Love co-star Cillian Murphy, is released in the UK later this year.

Michelle Williams is reportedly dating film director Spike Jonze.

The couple first met when the former Dawson’s Creek star auditioned for his 2006 film Where The Wild Things Are. She turned down the offer of the role but the pair worked together on Synecdoche, New York last year instead.

Star magazine reports that the couple were spotted kissing outside his Manhattan apartment earlier this month, with an onlooker telling the magazine: “Michelle kissed Spike with a closed mouth on the corner of his lips.

“There was definitely a bit of caressing going on. She was clutching his arm. The body language was very romantic.”

Michelle split from fiance Heath Ledger in September last year before his untimely death in January. Spike was previously married to Sofia Coppola and dated Drew Barrymore last year.

Christian Bale’s sister reportedly asked him for money before he allegedly verbally assaulted her and their mother at the weekend.

The Dark Knight star voluntarily submitted himself for arrested and questioning on Tuesday following the incident at his London hotel on Sunday night. Yesterday a source claimed the argument, which included Christian allegedly “pushing and shoving” his 61 year old mum Jenny, was sparked by Jenny insulting Christian’s wife Sibi Blazic - but now another source has said the insults only started flying after his sister Sharon asked for a six figure sum.

The source told the Sun: “Christian is a very wealthy young man and was asked to help his sister out financially.

“He was asked to loan her £100,000 but he refused and that caused an almighty row.

“During that row, the women claim, he assaulted them by pushing and shoving them. Both Jenny and Sharon are terribly upset over what happened.

“They did not want any publicity and the last thing they wanted to do was wreck his premiere evening [on Monday]. But they say he bullied them. They are both devastated that it has come to this but want him to be taught a lesson.”

The women reportedly the incident to police in Hampshire on Monday, who passed the case onto London colleague later in the day. However, other sources close to Christian suspect that the two women are jealous of his success and reported the incident in a big to sell their story.

Christian was released without charge on Tuesday and is continuing with the scheduled European promotional activities for the Batman film. He is expected to return to the police station in September.

Rumours about the couple started circulating recently, suggesting the pair have “been dating for months” hence her appearance in the brothers new video for their single ‘Burnin’ Up’ - but a spokesperson for the band said yesterday: “They are not girlfriend and boyfriend. They’re friends. All of the Jonas Brothers are friends with Selena.”

Selena herself added: “The Jonas Brothers are all sweet. They’re so amazing to me. They’ve become really good friends of mine, but I’m not dating any of them.”

Peaches Geldof has said she considers herself a strong person because of her difficult childhood.

The 19 year old’s parents Bob Geldof and Paula Yates divorced when Peaches was just six years old, then Paula died Peaches was 11.

The socialite, who is said to have nearly died from a drug overdose herself at the weekend, said recently: “I think I am a strong person. I’ve been through a lot in my life.

“But I’m not the type to dwell on things - I just try to move on.”

But moving on doesn’t mean forgetting: “I have 16 tattoos. I have them to commemorate moments in my life.

“I think it is amazing to be able to have something on my body that reminds me of a person, place or time.”

She added: “Where do I see myself in five years time? Hopefully married. I want to get married young.”
