This adorable duo never shies away from expressing their love on Twitter. Jessica posted this too-cute pic of herself planting one on her hubby on his birthday on Jan. 10, 2013, along with the message, "Happy Birthday my sweet love @CashWarren #HappyBirthdayCash!" Cash returned the favor a week later, on Jan. 18, 2013, when Jessica's lifestyle company, The Honest Company, celebrated its one-year anniversary. He proudly tweeted, "A year ago today The Honest Company was launched. So proud of @jessicaalba, her partners and the entire honest team! You ALL inspire me. Happy Birthday!"
