The celebrity guest list for the upcoming White House Correspondents’ Association Dinner seems to grow each day — Steven Spielberg! Michael Douglas! — and now even some of D.C.’s four-legged friends are getting in on the action.

[IMGCAP(1)]Pet care expert Wendy Diamond is hosting the White House Pet Correspondents Benefit on April 28 at Hotel Helix. Celebrity guests and their pets will raise money for the Washington Animal Rescue League (and Diamond will also promote her new pet-focused book, “It’s a Dog’s World”).

Canine lookalikes of first dog Bo Obama and (vice dog?) Champ Biden will be on hand, and celebs advertised for the event include astronaut (and recent “Dancing with the Stars” star) Buzz Aldrin and talk show host John McLaughlin.

Tickets for the benefit cost $50. Be warned: There will be animals up for adoption, so you might end up taking home a furry friend.
