Riley Keough returns home with her daughter after Lisa Marie Presley’s funeral

Riley Keough is back in Los Angeles after burying his mother Lisa Marie Presley at Graceland, and is revealing Lisa’s first grandchild, the daughter few people knew Riley gave birth to last year.

The actress stepped off a private plane Monday afternoon at the Van Nuys airport, her baby in her arms, marking the first time we’ve seen her daughter’s face in public.

Riley and her husband, the Hollywood stuntman, Ben Smith-Petersen, made surprise reveal about his daughter’s existence during the celebration of Lisa Marie’s life… when Ben read a letter Riley wrote to her mother, which referenced the girl.

The letter, which Riley titled “A Letter to My Mom,” reads in part… “I hope I can love my daughter like you loved me, like you loved my brother and sisters.”

Ben and Riley had never made it public that they had a baby, and Riley obviously did an excellent job of keeping her pregnancy private.
