Actress Jessica Alba and husband Cash Warren were all smiles and snuggles while out with their two daughters – Honor, 6, and Haven, 3 – on Sunday (February 8).

The family-of-four enjoyed the afternoon at Coldwater Canyon Park in Beverly Hills, Calif. After playing on the playground, the group were seen shopping nearby.

The Sin City actress, 33, recently opened up about being bullied as a teen, and how she will approach the tough topic with her own daughters.

“Growing up, whenever I was bullied, my mom would say, ‘You’re a beautiful girl,” Alba shared. “They’re just jealous. It never helped. I want my girls to know that beauty is being kind…beauty is helping people…beauty is humility.”

New mom Scarlett Johansson covers the March cover of W and opens up about family life with Romain Dauriac and their 4-month-old daughter Rose.

On her daughter: “When she came out of me, I was so surprised. I had a very strong picture in my mind of what my baby would look like. And, of course, she is completely different. Perfect, but not what I’d imagined. Now, of course, I can’t picture her any other way.”

On being a child star: “I had a big imagination. I particularly loved Judy Garland, and, to me, she did it all. For as long as I can remember, I wanted to be an actor. And I wanted to do everything. When you’re a kid, they send you on a lot of commercial auditions, and I was terrible at selling things. I never got those parts. I remember crying in the subway, and my mom said, ‘Look—let’s forget it. Do something else.’ And I replied, ‘No. You can’t take this away from me. I want to be an actor!’ Waiting for the B train, I had my come-to-Jesus moment.”

On playing the role of Black Widow in The Avengers: “I had done my research, and the Black Widow character resonated with me. She is dark and has faced death so many times that she has a deep perspective on the value of life…I think of her that way. Black Widow is a superhero, but she’s also human. She’s small, but she’s strong. It’s hard not to admire her.”
