She is married to standup comic Mike Lukas (of "The Straight Dope" fame), her "Gretchen and The Lukes" co-host. "Gretchen and the Lukes" airs on the Los Angeles station KLSX 97.1 Free FM Fridays from 11pm-1am and on San Francisco-based 106.9 Free FM Sundays from 9pm-11pm. Although Gretchen and Lukas do acknowledge being married on air, they are pretending that they are not married to each other for the show, which runs contrary to some Mike Lukas interviews published before the show's debut, mentioning specifically that he just married his longtime girlfriend in her hometown of Dallas, and in addition, Mike Lukas's old personal homepage (miKeluKas.com—offline as of late December 2005) identified Gretchen (in name and photos) as his longtime love.
