Despite an investigation by the state of Utah for felony bigamy, the husband featured on reality show "Sister Wives" has married a fourth wife, reports TMZ.com. 

The story says that Kody Brown has 21 mouths to feed after marrying Robyn Sullivan, who has three kids from a previous marriage and who joins Brown’s other 13 children and three wives in the family.

TLC, which airs the program, wasn’t permitted to tape the ceremony, but the wedding reception will be featured on the TV show, the story says.
