Wendy Diamond started planning a lavish wedding for her Maltese after learning Lucky had cancer.

It was intended as a tribute to her famous dog, and a way to raise money for a worthy cause.

When Lucky, who held the world record for being photographed with celebrities, died last month, Diamond — a TV personality, animal welfare advocate and founder of Animal Fair magazine — apparently decided the wedding should go on.

Last night it did, with a new bride — her rescued dog, Baby Hope. Diamond was hoping to break the Guinness World Record, as she did with her photographs of Lucky, by holding the most expensive animal wedding ever, and raise money for animals at the same time.

The nuptials took place last night at the Jumeirah Essex House — Baby Hope married Chilly Pasternak, a Virginia poodle chosen in an online vote — with proceeds going to the Humane Society of New York.

The extravagant touches included a $6,000 custom wedding dress for the tiny bride, a $5,000 sushi spread, and a $15,000 seven-piece orchestra, according to the New York Daily News.

Wedding planner Harriette Rose Katz, organized the event. Kleinfeld couture bridal designers Michelle and Henry Roth tailored a $6,000 two-toned, white French lace-encrusted dress with Swarovski crystals and a silk train for the bride. TLC’s “Cake Boss” based in Hoboken is making the wedding cake

The vendors donated their services. Some 250 humans and 50 dogs were expected to attend.

Diamond adopted Lucky in 1999, and the dog inspired her to launch her Animal Fair Media empire. She photographed Lucky with hundreds of celebrities as part of a campaign to stop shelters from euthanizing pets.

After Lucky died in June — while the wedding was being planned — Diamond decided that Baby Hope, a dog she’d been fostering, would make a fine bride.

Tickets to Animal Fair’s “Pet Wedding of the Century” started at $250, with “distinguished sponsors” forking over $10,000 for a table. The couple plans a honeymoon in the Hamptons.
