Gwyneth Paltrow grabbed her neon clutch and joined pal Gwen Stefani for a dinner out in London last night. Gwen and her family have been in the UK for the last week, though her days are usually filled with park outings alongside Gavin, Kingston, and Zuma Rossdale. The ladies stopped first at Gwen's place near Primrose Hill, then made their way to a Japanese restaurant closer to the city's center. Gwen and her family were also spotted paying a visit to Gwyneth and her husband Chris Martin's home in the Hampstead neighborhood on Saturday. It's a good time for the ladies to catch up and trade secrets, since Gwyneth is mulling over offers to create an album or even record a track with the British band JLS. Gwen's an expert when it comes to that area and recently logged long hours in the studio with No Doubt finishing its next record. Gwyneth, though, still has her big screen career to focus on and recently hinted during an interview with the BBC's Sunday morning news show Something For the Weekend that she may reprise her role as Pepper Potts in The Avengers and even make a cameo on the upcoming Glee tour.
