In a post titled, "Baby Makes 6!," Tori announced the big news, saying simply, "Dean, Liam, Stella, Hattie, and I are beyond thrilled toannounce that another little McDermott is on the way! We feel truly blessedthat another angel has found us. Love, Tori xoxo." She also posted the adorable photo above, of her children's hands on her pregnant belly.

Tori and Dean are already parents to Liam, who is 5, Stella, who's 3, and little Hattie, who was just born this past October! Dean also has an older son, Jack, from a previous marriage. Despite an unconventional start to their marriage (they began an affair on the day that they met, even though they were both already married), anyone who watches their reality show, Tori and Dean: Home Sweet Hollywood, knows that Tori and Dean are very much in love. And we couldn't be happier for them!

Do you think Tori and Dean's new baby will be a boy or a girl?
