Philips married Humphrey Bogart on April 3, 1928, at her mother's apartment at 24 Hopkins Street in Hartford, Connecticut, by a Justice of the Peace.

When Bogart began to gain film roles in Hollywood, Philips declined to move with him to California, as her stage career was firmly established in New York.

[2] Continuing with her stage career in New York, Philips then went on to marry her longtime friend, actor and director Kenneth MacKenna (August 19, 1899 – January 15, 1962), an American actor and film director, born Leo Mielziner, Jr. in Canterbury, New Hampshire, brother of five-time Tony winner, Jo Mielziner.

[2] Philips died at St. John's Hospital in Santa Monica, California, on April 22, 1975, aged 74, after a long battle with lung cancer.

Philips was godmother to the children of the Hackett family, sending them to camp in the summer time and visiting them in New England and in Dobbs Ferry, New York.
