Riley Keough and her husband Ben Smith-Petersen have secretly welcomed a baby girl, a representative for the actress confirmed to Fox News Digital on Sunday.
Smith-Petersen alluded to the news while reading a letter from the 33-year-old at a ceremony honoring his late mother-in-law, Lisa Marie Presley, held at Graceland.
“Thank you for showing me that love is all that matters in this life,” he read. “I hope I can love my daughter as you loved me, as you loved my brother and my sisters.”
“Thank you for giving me strength, my heart, my empathy, my courage, my sense of humor, my manners, my temper, my wildness, my tenacity,” the letter continued. “I am a product of your heart, my sisters are a product of your heart, my brother is a product of your heart.”

Keough’s representative did not provide further details, including when the baby was born or her name.
Smith-Petersen and Keough said “I do” in 2015.
Hundreds of people gathered on the front lawn of Graceland in Memphis, Tennessee, to mourn the death and remember the life of Elvis Presley’s only child.
Lisa Marie, a singer-songwriter who devoted her life to her father’s legacy, died on Jan. 12, hours after being hospitalized for a medical emergency. She was 54. Lisa Marie is survived by three daughters, including Keough.

Some mourners held flowers as they waited for the service to begin under the tall trees on the lawn of Graceland, the home where Lisa Marie lived with her father as a child. The mansion she owned has been turned into a museum and tourist attraction that hundreds of thousands of fans visit each year to celebrate the life and music of Elvis, who died in 1977.
“We would like to express our sincere gratitude for the love, compassion and support you have shown our family during this difficult time,” said a message from the Presley family on the program for the service. “We will always be grateful.”
Among those who appeared at the service were Priscilla Presley, Sarah Ferguson, the Duchess of York, as well as singers Billy Corgan, Alanis Morissette and Axl Rose.
