Newlyweds Pete Wentz and Ashlee Simpson have announced a new addition to their family. The Fall Out Boy rocker has posted their new 10-week-old puppy on his website.

Wentz writes:

"the newest addition to the family. Meet rigby. Shes ten weeks right now and pretty much follows hem around." - sic

The bassist, who turned 29 on June 5, also showed a picture of his birthday cake, which is in the likeness of his older dog, Hemingway. The English bulldog was the ring-bearer in Wentz and Simpson's wedding last May.

With pregnant Simpson's baby is due in the fall, they might practice their parenting skills on Rigby first before their real baby comes.
