Last month, Hailey filed to register "Hailey Bieber" for the purposes of a clothing line. She also registered her maiden name, "Hailey Baldwin," as well as "HRB3," under her company, Rhodedeodato Corp. Hailey and Justin married in September during a visit to a New York City courthouse.
"The couple kept their marriage a secret from a lot of people. Justin and Hailey wanted to be married, and didn’t want to wait. They still plan to have a more formal wedding, but for them this intimate ceremony was exactly what they wanted," a source told ET last month.
