Lauren Alice Koslow is an American actress, best known for her long-running portrayal of Kate Roberts on the soap opera Days of Our Lives, which she has played continuously since 1996. She has also appeared in the soaps The Bold and the Beautiful and The Young and the Restless.
Early life and education Koslow was born in Boston, where she spent the early years of her childhood.
Career She began her acting career with touring theatre work in such productions as Cat on a Hot Tin Roof and Dial M for Murder.
Turning to television in the mid-1980s, Koslow was cast in the role of Lindsay Wells on the CBS soap opera The Young and the Restless, which she played from 1984 to 1986. She was then asked by the serial's creators William J. Bell and wife Lee Phillip Bell to become an original cast member on the duo's new sister soap The Bold and the Beautiful which debuted in the spring of 1987. She portrayed fashion designer Margo Lynley from the serial's inception until 1992, and later filmed a cameo flashback sequence as the character in 2002.
Through the early 1990s, Koslow had guest-starring roles in several prime time series, including Silk Stalkings and The Nanny. She returned to daytime television in 1996, replacing actress Deborah Adair on NBC soap Days of Our Lives, after Adair's departure from the series in February 1995.
Koslow assumed Adair's role of vindictive call girl turned corporate executive Kate Roberts on Days of Our Lives. The character is known for her wickedness and deception, specifically her ongoing war with fellow Salem resident Sami Brady (Alison Sweeney), the former ex-fiancé of Kate's son Austin (Austin Peck) and ex-fiancé/current ex-wife of her son Lucas (Bryan Dattilo), and numerous affairs and romantic entanglements. Other notable character conflicts include Kate's mysterious past with series villain Stefano DiMera (Joseph Mascolo), her rocky marriage with mogul Victor Kiriakis (John Aniston), and her rivalries with crazed socialite Vivian Alamain (Louise Sorel) and Nicole Walker DiMera. Kate is the mother of Lucas Horton, Rex Brady, Cassie Brady, Philip Kiriakis, Billie Reed, and Austin Reed.
