and Ashlee Simpson-Wentz
have a new addition to their family: a 10-week-old puppy.
"The newest addition to the family. Meet Rigby," writes Wentz about their new pet
Wentz is known for his love of pets: His dog Hemingway was the ringbearer for his May wedding to Ashlee
, who showed off her baby bump at Wentz's bar opening
And luckily, Rigby loves Hemingway just as much. "[She] pretty much follows Hem around," says Wentz.
But for his 29th birthday on June 5, he also commissioned a cake that was a life-size replica of Hemingway
"Kinda weird to eat your dog," writes Wentz. "But I got past it."
