Has Kristen Bell quietly become Mrs. Dax Shepard, or did she just jump the nuptial gun a wee bit? On Wednesday night, the actress posted a picture of her funnyman fiancé, phone in hand and the TV on in the background, with the caption, "My adorable husband, @daxshepard1 voting 4 his favorite american idol. Over and over again." So, did the couple, who became engaged in late 2009, secretly get hitched? Not according to Bell's rep, who tells Us, "They are not married, but they refer to each other as husband and wife."
