But that's just a word she uses sometimes. They're not actually married!
Bosworth's rep tells E! News that the Movie 43 star and her director fiancé have not taken the plunge just yet. Hubby is just a term of endearment the actress uses for Polish sometimes, the rep says.
"My hubby, the baker," Bosworth had tweeted yesterday along with a pic of Polish in the midst of whipping up some goodies in the kitchen.
And this isn't the first time her everyday habits have led to marriage rumors.
Even before she and Polish were engaged, Bosworth often wore a thin gold band on her wedding finger, prompting speculation that they had already made things official.
It wasn't until August that Bosworth let it slip that her relationship had progressed, calling Polish her "fiancé" in a travel-blog essay she wrote for Vogue.com.
And fiancé proved to be more than just a term of endearment.
