Maria Rosario "Chat" Silayan (b.1960 - April 23, 2006) is an actress, TV host, and a former Binibining Pilipinas- Universe titleholder. She got the third-runner up place in the Miss Universe Pageant held in South Korea in 1980.
Chat Silayan is the daughter of great actor Vic Silayan and Antoinnette Rivera. Her dusky splendor captivated the discerning judges of the 1980 Miss Universe Pageant in Seoul, Korea, where she notched the Third runner-up honor.
During the pageant, host Bob Barker asked Chat whether she wanted to become an actress like her famous father. Chat half-heartedly said, " No! Because the movies are not good for women."
But even if her life was moving at a very fast pace, she did not overlook her studies. She willed herself to finish school. She, in fact, was a registered nutritionist-dietitian.
Chat married Mike Bailon on December 30, 1992, when she was 33 years old. Previously, she had an unsuccessful three-year relationship with Euro filmmaker Edoardo Margheriti. They had a son, Victor Anthony, now 22. Edoardo was not able to visit Chat in the hospital before she died. A meeting which was arranged by Mike, Chat’s devoted husband of fourteen years however Edoardo arrived 1 day late.
In the movies, Chat was last seen in "My First Romance" (2003). She also co-hosted "700 Club Asia," with Dulce and Peter Kairuz. Her other films included "Kamakalawa," "Kung Ako Na Lang Sana" (2003), "Esperanza: The Movie" (1999), "Ipaglaban Mo: The Movie Part 2" (1997) and "Dyesebel" (1990).
Chat Silayan died in her sleep last April 23, 2006 after a two-year battle with colon cancer. She is survived by her husband Mike and their three children: Victor Anthony, Timothy and Micaela. She was only 46.
