Denise Richards and Charlie Sheen show a united front on Saturday in Calabasas, Calif., where they ate breakfast and then shopped at a local jeweler, Polacheck’s. “We’re working toward getting back together and fixing things,” Sheen recently told David Letterman. In March, Richards filed for divorce after three years, but the pair have been together often since the birth of their second daughter, Lola, in June.

Bridget Jones could relate: Renée Zellweger looks blue on her way out of a New York City hotel on Monday. Last week, the actress filed to annul her four-month marriage to Kenny Chesney, citing “fraud” – although she later issued a statement insisting that “the term ‘fraud’ … is simply legal language and not a reflection of Kenny’s character.”

As her fiancé, Adam “DJ AM” Goldstein, looks on, Nicole Richie makes a wish at the Teen Vogue Young Hollywood Issue party at the Hollywood Roosevelt Hotel on Tuesday. Richie turned 24 the next day, Sept. 21.

Guy Ritchie listens up at the London premiere of his new movie, Revolver, on Tuesday. (Some fans booed the director and wife Madonna when they didn’t sign autographs.) The Roberto Cavalli-clad Madonna told reporters she was glad the film was finished: “I get more love when he’s not making a movie.” She also said the sling she’s worn since a horse-riding accident last month would be off within a week.

An elegant Nicole Kidman shows she’s a master of Italian dressing while leaving her hotel in Rome on Tuesday. The actress was in the city for an appearance on an Italian TV show.

Brad Pitt does a world of good at the Clinton Global Initiative forum in New York City on Saturday. (Also in the house: Pitt’s girlfriend and longtime activist Angelina Jolie.) The event, organized by former President Bill Clinton to address issues such as poverty and climate change, raised more than $1 billion in pledges (admission alone was $15,000 a person).

Things look to be on-again with Jude Law and Sienna Miller, who clasped hands and spent Saturday evening in London celebrating her last performance in As You Like It by hitting clubs and dancing until dawn.

Playing the dutiful husband – and proud papa – Kevin Federline loads the car outside Santa Monica UCLA Medical Center on Friday, two days after Britney Spears gave birth to their son there. Federline later helped his wife of one year make a quick getaway to their Malibu home.

Beyoncé, in a design from her own House of Dereon, glides down the runway to a standing ovation during the Fashion for Relief show in New York on Friday. Naomi Campbell put together the all-star runway benefit to aid victims of Hurricane Katrina.

Jodie Foster holds tight to costar Marlene Lawston at the Los Angeles premiere of their film Flightplan on Monday. Foster plays the newcomer’s mom in the missing-in-midair thriller, which opens Friday.

Two J.T.s – Justin Timberlake and James Todd Smith, a.k.a. LL Cool J – yuk it up at the Toronto Film Festival on Saturday for the closing-night screening of their movie, Edison. In the film, Timberlake plays a rookie journalist investigating police corruption and LL Cool J plays a conscientious cop.

Lenny Kravitz and his daughter, Zoe, 16, prove that boho-chic fashion sense runs in the family at Gwen Stefani’s L.A.M.B. runway show in New York City on Friday. (Zoe’s mom is Kravitz’s ex-wife, Lisa Bonet.)

Mariah Carey and Brittany Murphy steal the spotlight Monday at a dinner party for the newly refurbished Versace London store.

Showing off her bare ankles, Martha Stewart arrives at the Late Show with David Letterman in New York on Monday. “I faced what I had to face,” she told the talk-show host of her incarceration. “I lived through it, actually, with flying colors, if you can live through ‘Yale’ (her euphemism for prison) with flying colors.”
