Elizabeth Andrea "Bitsie" Tulloch is an American actress born on January 19, 1981, in San Diego, California. She spent her childhood in Spain, Uruguay, and Argentina, and her nickname "Bitsie" is a tribute to her grandfather, a World War II bomber pilot who was involved in the 1961 Goldsboro B-52 crash.
Tulloch began her acting career under the name "Bitsie", but in 2017, she decided to use her given name Elizabeth for billing purposes. She stated that she still introduces herself as Bitsie to people she meets, but wanted to switch to Elizabeth to reflect her growth as an actress.
Tulloch is of Scottish and Spanish ancestry, and her first language was Spanish, although she no longer considers herself fluent. Her paternal grandmother's family is from Renfrewshire, Scotland, and her grandfather's family originated from the area around Kirkwall, Scotland.
Tulloch graduated magna cum laude from Harvard University with a double major in English and American Literature and Visual and Environmental Studies. Her first acting credit was as R2-D2's "girlfriend" in R2-D2: Beneath the Dome, a mockumentary produced by George Lucas.
She has appeared in various films and television shows, including Lakeview Terrace, Losing Control, Alpha and Omega, and the CW's Arrowverse shows, including Superman & Lois, where she plays the role of Lois Lane.
