Laura Leighton joined “Pretty Little Liars”
One of the most successful original members of “Melrose Place,” Sydney Andrews was Laura’s character, and she turned into a full-on cast member after showing up in just a couple of episodes. Her first gig after departing was in “Beverly Hills, 90210” but in 2010 she graced our screens in PLL, remaining on the show until it ended in 2017. In “2021” she made appearances in two reboots: “Fantasy Island” and “Dynasty.”
