Lena Dunham took to Instagram to grieve late co-star Nick Lashaway, who made a guest appearance on her show Girls. The 28-year-old actor was killed in a car accident on May 8.

“Nick was such a talented, funny and kind person and we were so lucky to have him as a part of our Girls family when he played Frank in episode 207," she wrote alongside a pic of them working together on the HBO series.

"We will always remember the week we shared with him, his playful smile, his easy instincts, how much he made us laugh even when we had to stay up all night in the woods," she added. "We are sending love to his family and friends and feeling such gratitude for his gifts.”

Nick was involved in a three-car crash in Framingham, Mass., and was found unconscious behind the wheel of his Jeep, which was on fire.

Despite a retired officer and his two sons pulling him from the vehicle and performing CPR, he was later pronounced dead after being taken to a hospital, MetroWest Daily News reports.
