Maggie Gyllenhaal is in talks to appear in new Batman movie The Dark Knight.

The Donnie Darko actress is being lined up to play Rachel Dawes, the role made famous by Katie Holmes in 2005's Batman Begins.

Christian Bale, Michael Caine, Morgan Freeman and Heath Ledger have already signed to appear in the film.

The Dark Knight is scheduled for release next spring or summer.

Johnny Depp's daughter has been allowed to leave hospital after nine days.

The Pirates Of The Caribbean actor and his partner Vanessa Paradis have taken seven-year-old Lily-Rose back to their London hotel.

A spokesman for Depp said: "We are happy to report their daughter is doing much better. The family greatly appreciates the continued support."

An onlooker told The Mirror: "Johnny and Vanessa looked exhausted."

The precise nature of Lily-Rose's illness remains unknown.

As her July 7 wedding to Tony Parker draws nearer, Eva Longoria has a surprise to spring on the event's entertainer.

"My friend Kenny [Chesney] is going to sing at my wedding, the Desperate Housewives star tells Cosmopolitan for its April issue. Except there's one snag: "He just doesn't know it yet," Longoria admits.

As for what is already planned, Longoria, 31, looks forward to having a family, though when it will start may still be open to discussion.

"I never had a timeline for my life. I didn't say I wanted to be married at 28 and have three kids by the time I was 32," she says. "I do want to have a family at some point. I also want to adopt. I don't feel pressure to have kids because I know there are so many out there."

Asked what excites her most about the wedding to come, Longoria exclaims, "My dress, my dress, my dress! I wish I could wear 10 dresses to my wedding. It's so sad that you put it in storage and then never see it again."

She has a remedy for that, though: "I am going to sleep in mine after I wear it."

Longoria is far more serious when discussing how she and San Antonio Spurs point guard Parker deal with conflict. "We never go to bed angry, which sometimes frustrates Tony because he'll be like 'Please. I have a game tomorrow. I need sleep,' " she says.

"Another rule we have is that nobody is ever right. I don't need to be right. I just want to be understood. The same goes for him," she adds.

One argument they don't have, she says, is over her male pals. "I get so much crap for having friends like Jamie Foxx and Mario Lopez, who are like brothers to me. It's difficult when you're in an insecure relationship or if your partner doesn't know where he stands with you. That's not how it is with [Tony and me]."

Former Melrose Place costars Heather Locklear and Jack Wagner have been spotted together multiple times – even holding hands – but pals say the two aren't starting a Hollywood romance.

"[They] have been friends since Melrose Place," a Wagner pal reveals, referring to the '90s prime-time soap in which the pair played lovers who ended up marrying. "There's definitely no change in their relationship. They [just] went out with a bunch of her friends."

The old friends have more in common than they used to, though. Locklear, 45, is seeking a divorce from Bon Jovi guitarist Richie Sambora, with whom she has a 9-year-old daughter, Ava. Wagner, 47, is a single parent of two sons, Peter, 16, and Harrison, 12, having divorced his wife, Kristina, in 2006.

After her breakup with Sambora last February, Locklear seemed to have found romance with David Spade, yet a source says, "David saw her through some really sad times, but they were never more than friends."

Perhaps Wagner (who currently plays a sea captain on daytime's The Bold and the Beautiful) is following suit – at least when it comes to platonic PDA with Locklear.

According to an onlooker who spotted the actors sharing some crispy-noodle prawns at Mr. Chow on March 1, "they were holding hands and really focused on each other."

Those who know Heather say entwined fingers do not a relationship make. "She holds her friends' hands all the time," says a pal. "Men, women – it doesn't mean anything."

But if their relationship does heat up, Wagner's already got the green light from Locklear's friend, who ticks off a list of the singer-actor's sexy traits.

"He's super funny, charming, considerate and a little irreverent," she says. "I don't think anyone would be sad if [something more] happened."

Double the good news for Salma Hayek: The actress is engaged to businessman boyfriend François-Henri Pinault – and she's pregnant.

"Businessman, François-Henri Pinault, and his fiancée, Salma Hayek, are happy to announce they are expecting the arrival of their first child," Hayek's rep confirmed in a statement Friday.

The news, first reported by New York Daily News columnist Ben Widdicombe, comes just days after a photo of Hayek made the Web rounds prompting speculation that she was expecting.

The pair have kept a relatively low profile since their relationship began – though Hayek, 40, has joined Pinault for occasional public events, including one in April at the festivities surrounding the inauguration of the Pinault Foundation's Modern Art collection in Venice's Gritti Palace.

Pinault, 44, is the CEO of luxury goods firm PPR, which owns Gucci and Yves Saint Laurent, as well as a French department store and national music chain. His father, François, is an avid art collector owning more than 2,500 valuable pieces, including Picassos, Miros and work by contemporary artitsts including Damien Hirst. Familiar on both European and American fashion and art circuits, the family fortune is estimated in excess of $7 billion.

Pinault, who was once linked to Nicole Kidman, was previously married and has two children.

Hayek has most recently had her hands full on Ugly Betty, both as a guest star and as the executive producer of hit ABC show. Hayek previously dated actor Edward Norton for four years until 2003, before linking up with Josh Lucas, with whom she split in 2004.
