Moviestore Collection/Rex/REX USAPatrick Dempsey is paying tribute to his late Can't Buy Me Love co-star, Amanda Peterson.
"In my memory, she will always be vibrant and young," the former Grey's Anatomy actor wrote on Twitter. "Gone too soon. Sending my thoughts and prayers to Amanda's family."
E! News confirmed yesterday that Peterson passed away at the age of 43 and was found dead at her Colorado home by the local police department.
Officers were sent to her home after family members became concerned after not hearing from her for several days. Peterson's cause of death is still under investigation.
Peterson's father, however, told TMZ that "she had some illness and a sleep apnea problem that may have contributed."
Additionally, the site reported that Peterson had been dealing with several medical issues over the last two years, including pneumonia and sinusitis.
Her father further shared that the late actress had been living in a home with mold issues but moved off the property approximately one year ago.
Peterson shot to fame with her blonde cheerleader role as Cindy Mancini in the hit 1987 flick with Dempsey, but she got her start in Hollywood way earlier than that.
The actress made her big debut in Hollywood at age 9, when she won a role in the musical Annie.
One year before Can't Buy Me Love hit theaters, Peterson won the Young Artist Award for Best Young Actress Starring in a Television Drama Series for her stint on Boone.
And after nearly two decades in Tinsletown, Peterson packed her backs and moved back to her home state of Colorado, where she reportedly went back to school and briefly modeled.
Our thoughts go out to her friends and family.
