Liv Tyler is taking pregnancy in stride. Currently expecting her second child with fiancé David Gardner, she's shared a glimpse at her growing bump.

The 38-year-old actress took to Instagram on Sunday with a photo of herself and model Frankie Rayder frolicking in LA. Casting shadows on a wall, the two friends are seen reaching for each other's hands as Tyler lifts her T-shirt to reveal her baby bump. "LA afternoon walks with ma-baby and my frank #frankierayder," she captioned the sunny photo.
