I think they want to keep their relationship private which is a very smart thing to do.
Here's a photo of them. They're a lovely couple.
Aisha Tyler and her husband Jeff Tietjens met at Dartmouth.
Together they moved to Oakland after graduation into a mostly African American section of town.
Shortly after that ,the two moved to San Francisco. But by the late 1990s, they had moved to Los Angeles. By 2001, Tyler was hosting E!ís Live Countdown to the Academy Awards. Jeff is reportedly a lawyer in Los Angeles.
