Tori Spelling and actor/husband Dean McDermott are expecting their third child.

The TV heiress made the big announcement via Twitter. "I know there's been a lot of speculation, so I wanted everyone to hear from me... Its official...Dean & I are PREGNANT!!!!"

Pregnancy rumors were sparked over the weekend when Tori appeared at the GLAAD awards showing off a tiny baby bump.

The latest little McDermott will join brother Liam, 4, and sister Stella, 2∏. Dean also has a son Jack, 12, from a previous marriage.
