Gwyneth Paltrow had her phone in hand as she left a building in Santa Monica today in white jeans and a denim shirt. The actress has been spending much of her time in and around LA in recent months, from presenting at the Academy Awards in February to partying with her good friend Stella McCartney at the designer's West Hollywood boutique last weekend. At the Oscars, Gwyneth took the stage with her costar in The Avengers, Robert Downey Jr. Gwyneth will be reprising her role as Pepper Potts to Robert's Iron Man in the superhero film, which hits theaters later this month. She didn't join her costars at the Hollywood premiere of the project two weeks ago and also skipped their promotional tour in Europe this week given her relatively small part in the project. For now, Gwyneth's husband, Chris Martin, is the one doing the traveling in the family. Coldplay is on tour, and the band has been playing dates in Canada all week.
