(CBS) - Tori Spelling is going to be a mom again.
The reality star and husband Dean McDermott are expecting their third child together.
"I know there's been a lot of speculation, so I wanted everyone to hear from me," Spelling, 37, wrote on her Twitter feed Monday. "It's official...Dean & I are PREGNANT!"
Spelling, a "90210" alum, flaunted her small baby bump while at the 22nd Annual GLAAD Awards in Los Angles on Sunday.
She and McDermott, 44, have two children together: son Liam, 4, and daughter Stella, 2. McDermott is also the father to son Jack Montgomery, 12, with Canadian actress Mary Jo Eustace.
The couple, who married in May 2006, are currently the stars of Oxygen's "Tori &Dean: sTORIbook Weddings," which airs on Wednesday.
