Former ’90210′ star Tori Spelling and her husband, actor Dean McDermott, just got a little more fodder for their TV show.

On Tuesday, Spelling tweeted that the couple welcomed their third child, named Hattie Margaret, on October 10.

She joins big brother Liam, 4, and older sister Stella, 3, along with two half-siblings from her dad’s previous marriage.

The sixth season of Spelling and McDermott’s reality show, ‘Tori & Dean: Home Sweet Hollywood,’ premieres November 29 on the Oxygen network.
