Sara Rue will marry her longtime fiancé
Kevin Price in a beachside ceremony Saturday – and after months of "stressful" planning, the Shedding for the Wedding
host is ready to indulge.
"I'll be having one of each," Rue, a Jenny Craig spokeswoman, tells PEOPLE of the three wedding cakes planned for the nuptials, including a red velvet and a pumpkin caramel confection. "Tiny slivers!"
When Rue, 33, ties the knot with Price, 35, at oceanfront club in Pacific Palisades, Calif., the actress – who has lost over 50 lbs.
in the past year – will show off her svelte figure in a coffee-colored Amsale dress.
Details of the hummingbird and butterfly-themed nuptials
, which was planned by Rachel Hollis, include the bride's butterfly-adorned Aruna Seth shoes and butterfly brooches that the bridesmaids will pin onto their vintage dresses, which Rue found after searching "all over Los Angeles," she told PEOPLE at a City of Hope event earlier this month.
Following the ceremony, Rue is looking forward to the reception where, "I can just relax, dance, and be with my family and friends" at a beer pong bash, she says.
"We met at a Fourth of July party and Kevin taught me to play," the bride says of the drinking game inspiration for their reception. Rue and Price spent hours of "blood, sweat, and tears," in their backyard creating a customized beer pong table and paddles, stenciling butterflies on them with spray paint.
As for the cuisine, guests will be served healthy vegetarian options as well as latkes (potato pancakes) and other traditional Jewish dishes that Rue has loved since childhood.
After the deejay spins his last track, the newlyweds will jet to French Polynesia for a romantic honeymoon where Rue plans to "flounce around in tiny shorts and a bikini top," she told PEOPLE recently.
This will be the second wedding for Rue, who divorced writer Mischa Livingstone, in 2008.
