Rumer Willis was seen shopping in West Hollywood with a friend. The 23-year-old entertainer kept it casual in short shots with flannel and cowgirl boots, she looked fresh and sexy. Rumer tweeted about her upcoming movie earlier this week, saying, “So excited to be at the Miami Film Festival to support my movie Diary of Preston Plummer.” The movie is a romantic drama starring Trevor Morgan as Preston, a college graduate searching for something to love.
