Jessica Alba shares throwback photos of herself with look-alike younger brother Joshua

Jessica Alba never forgot to greet her younger brother Joshua Alba a 'Happy National Siblings Day', and this year was no different.

Jessica has always been close to her family, and this is evident by how she would always share photos with her family whenever she can.

In this year's National Sibling's Day post, Jessica could be seen in the photograph with a younger version of her father, and her brother as a baby.

For Alba's birthday just a few days ago, she seems to have spent it with her family, saying that her family is the best.

In a fun and quirky boomerang snap, she and her family members, including her husband Cash Warren, moved back and forth as they took the shot.

"Family is the best! Feeling all the Love @cash_warren@leavefootprintsoflove @cathyalba@markdalba #itsmybirthday #taurus"

Last Easter, the Alba family also spent time together, celebrating the festivities as one family. While everyone seemed to be having a great time, Jessica's husband and children were absent. However, the 'Fantastic Four' actress mentioned how she was missing her husband and kids.
