Jessica Alba and her husband Cash Warren took their two adorable daughters to the beach over the Labor Day weekend. The family packed up all the necessities for sand castle building and spent Sunday afternoon in Malibu, Calif., with their daughters Honor and Haven.

Alba dipped her toes in the ocean with her children, and the purple bikini-clad star even shook off the sand in a red bouncy house.

The actress wasn't the only star to take advantage of the last official summer weekend of the year. On Sunday, singer Robin Thicke and his 3-year-old son hung out at the Fountainbleau hotel in Miami while he traveled there for a Labor Day concert.

"Nashville" star Hayden Panettiere also enjoyed the holiday weekend in Miami where she let loose with some friends at the beach.
