Jessica Alba and Cash Warren "Working hard to repair their relationship"

Actress Jessica Alba and movie producer Cash Warren, who broke-up (albeit for a very short time) last month, have been on several romantic dates and are determined to repair wounds in their relationship, and "make things work this time."

Alba and Warren seen strolling along California's Pacific Palisades beach and dining at their favorite Malibu restaurants.

The pair arrived to a warm welcome at Malibu's Taverna Tony last Saturday..

Tony Koursaris, owner of Taverna Tony, told Us magazine: "I said to them, 'I'm so happy to see you here!' And they both said, 'We're happy to be here too!' "

On Sunday, Jessica and Cash kissed and held hands over lunch at Beverly Hills Le Pain Quotidien restaurant, before heading to Malibu's Nobu restaurant for dinner later that night.

Friends of the couple have claimed the pair were "miserable" without each other, and are visiting one of their favorite places in a bid to regain the spark they had when they first began dating.

A friend of the couple said: "Cash has been miserable since they split. And I guess Jessica was also missing him."
