Actresses Anna Paquin and Melissa Joan Hart and musician Taylor Hanson have all announced they're expecting additions to their families.

"True Blood" star Paquin, 29, and her husband and co-star Stephen Moyer, 42, told Entertainment Weekly they were having their first child together this fall. Moyer has two from previous relationships.

Hart, 36, best known for the 1996-2003 sitcom "Sabrina, the Teenage Witch," tweeted the same day that she and husband Mark Wilkerson are expecting their third child, who joins sons Mason, 6, and Braydon, 4. "(Early) Happy Birthday to me! And baby makes 3!" she wrote.

And Hanson, 29, told People magazine yesterday that he and wife Natalie, 28, have a fifth child due in late 2012. "Natalie and I are so anxious to meet our fifth mini-Hanson," he said. "As are the four siblings at home who are counting the days to the arrival."
