Lourd played the role of Lieutenant Connix in the 2015 Star Wars sequel film The Force Awakens. She will also appear in the next installment, Star Wars: The Last Jedi.
In February 2015, Lourd was cast in the Fox horror-comedy series Scream Queens. Lourd's character, a rich and disaffected sorority girl known as Chanel #3, wears earmuffs as an homage to Fisher's iconic "cinnamon buns" hairstyle from the original Star Wars film. In December 2015, Lourd spoke about her initial meeting with Scream Queens creator Ryan Murphy:
By December 2015, Lourd had joined the cast of the American biographical crime-drama film Billionaire Boys Club, alongside her Scream Queens co-star Emma Roberts. Lourd was cast as Rosanna, love interest of Kyle Biltmore, played by Jeremy Irvine.
Lourd returned to Scream Queens for its second season. This sparked her recent relationship with Taylor Lautner.
