Jessica Alba shares photo of her 2 daughters: 'My baby girls'

Alba's daughters Honor and Haven are ready to take on the 10th and 7th grade.

Jessica Alba's daughters are growing up so fast.

The "Honey" actress and Honest Company co-founder, 42, took to Instagram on Monday to share a snap of daughters Honor, 15, and Haven, 12, ready to tackle 10th and 7th grade, respectively.

Reminiscing in the caption, she wrote, "10th and 7th -where did the time go… (sigh 💔) my baby girls first day of school!"

She also added hashtags #momlifeisthebestlife, #summerisofficiallyover and #firstdayofschool.

Both photos Alba shared show Honor with her arm around Haven, but the girls are giving a bigger smile in the second while giving a more serious look in the first.

Alba recently stepped out with the whole family, including husband Cash Warren and their 5-year-old son Hayes, at one of Taylor Swift's Eras Tour stops in Los Angeles.

Alba and Warren, who tied the knot in 2008, celebrated their 15th wedding anniversary in May.
