Sally and Billy's parties may go wrong on The Young and the Restless

Sally's bachelorette party will have a surprise guest

Two big events are set to take place soon in Genoa City. Sally Spectra's (Courtney Hope) bachelorette party will begin at Society on Thursday on The Young and the Restless. Fans know that something will take place to interfere with the women and also Billy Abbott's (Jason Thompson) bachelor party.

The guest list for the women includes Abby Winters (Melissa Ordway), Chelsea Lawson (Melissa Claire Egan), Audra Charles (Zuleyka Silver), Victoria Newman (Amelia Heinle) and Claire Newman (Hayley Erin).

Traci Abbott (Beth Maitland) and Lily Winters (Christel Khalil) will arrive later and the main attraction will be Sally's younger sister Coco Spectra (Ashley Campbell) who will be so late her sibling thinks she is not coming.

Chloe Mitchell Fisher (Elizabeth Hendrickson) was mentioned but she will not be returning for the shower or wedding which angered some fans.

The Bold and the Beautiful fans will recall the character of Coco debuted with Courtney Grosbeck in the role. She was an intern at Forrester Creations and was dating RJ Forrester now portrayed by (Brayan Nicoletti).

Since leaving B&B Courtney Grosbeck has been on the television series Love Life, The Pitt, Homeland and Lincoln Rhyme: Hunt for the Bone Collector. As Courtney she was a sweet teen who was only around for a summer romance.

Spoilers have not said what her personality is like now that she is older but there are suppose to be fireworks at the shower. Perhaps it will be revealed that Victoria is dating Kyle Abbott.

It would be just like Audra to accidentally on purpose drop that bombshell to hurt Claire and Viki. Viewers are not fond of these two as a couple and are waiting for them to be exposed. No one, however, wants to see Claire devastated, except Ms. Charles.

Perhaps Sally's Aunt Shirley Spectra (Patrika Darbo) might show up unexpectedly, and cause chaos. Earlier spoilers revealed that she and Coco were coming to Genoa City but Aunt Shirley is not on the guest list for Thursday.

Her arrival could throw things off since a surprise guest is suppose to stun everyone. Shirley did not associate with the rich and famous in the fashion industry, How will she fit in with the elite in Genoa City.

There is also the chance the Sally could go into premature labor so anything is possible.

Y&R spoilers have not revealed of Coco and Shirley will stick around. Days of Our Lives viewers have been waiting for Darbo to reprise her role as Nancy Wesley and return to Salem.

The ladies will receive some troubling news which will leave them concerned. This may be about Patty Williams (Stacy Haiduk) who viewers wish would go away permanently.

Will Billy wreck his own bachelor party?

At the Abbott Mansion Jack Abbott (Peter Bergman) will be in charge of making sure Billy’s celebration goes off without a hitch, Kyle Abbott (Michael Mealor) and Michael Baldwin (Christian LeBlanc) will arrive and do their best to make Billy's big night memorable.

Drama may come in the form of Cane Ashby’s (Billy Flynn). Cane and Billy are like oil and water and usually do not get along. They could get into it or perhaps Cane will decide to play nice for the evening. There is also the possibility that Billy could somehow sabotage his own bachelor party.

The big question is whether Billy and Sally will make it down the aisle as planned. Could something happen to delay the wedding? The Young and the Restless fans should tune in on Thursday and Friday to se what happens.
