Tori Spelling and her husband Dean McDermott are expecting their fourth child, the actress announced on March 23.
"Dean, Liam, Stella, Hattie, and I are beyond thrilled to announce that another little McDermott is on the way," Spelling wrote on her official website. "We feel truly blessed that another angel has found us. Love, Tori xoxo."
Along with the blog post, which was titled "Baby Makes 6!," Spelling posted a photo of her baby bump, with her three children's hands on it.
The couple welcomed their youngest daughter Hattie five months ago, on October 10, 2011. Spelling and McDermott, 45, got married in 2006 and have a son Liam, 5, and a daughter Stella, 3. McDermott also has a son named Jack, 13, from his previous marriage.
The 38-year-old reality star made headlines in November after McDermott accidentally posted a photo of her breasts, as she was lying topless in the background of a photo of their son Liam.
At the time, Spelling said that even though it was embarrassing, she was glad that at least her breasts were in top form.
"If you are ever going to have someone tweet a picture of your boobs, I would rather it happen now than any other time because when you are nursing, your boobs look better than ever, bold [and] beautiful." Spelling told CNN. "I just had my nipples insured, so yeah, it's good."
The couple told Access Hollywood in November that they planned to have a fourth child soon.
Spelling rose to fame as a teen star in the drama series "Beverly Hills, 90210," and has since appeared in several reality shows with McDermott including "Tori & Dean: sTORIbook Weddings" and "Tori & Dean: Home Sweet Hollywood."
"It is a great job if you can even call it a job. It's amazing," Spelling told CNN. "And when people say like, 'Oh you put your kids on a TV show?' It's like, well, there is the option that I could be on a scripted TV series, I could be on a set somewhere 17 hours a day and I could not see my children at all."
The sixth season of "Tori & Dean: Home Sweet Hollywood" premiered on November 29 on Oxygen at 10 p.m. ET.
