Joe Jonas & Sophie Turner
For Nick and Priyanka's grand nuptials, the focus is on the family. So it makes sense that Joe and his loving fiancé are helping the soon-to-be-married couple celebrate the special occasion.
Jonathan Tucker
Nick's Kingdom co-star is one of the only groomsmen that are not blood-related to Nick, but with a friendship like theirs, they might as well be brothers.
Kevin & Danielle Jonas
Joe and Danielle, along with their daughters, will be taking part in the beautiful ceremonies that Nick and Priyanka have planned for their many guests.
Frankie Jonas
The "Bonus Jonas" is taking his rightful place alongside his brothers as a groomsman at the Christian wedding.
Chord Overstreet
The former Glee star and close pal of Nick's was photographed arriving in India for the wedding festivities.
Dwayne "The Rock" Johnson
A source tells E! News this A-lister is a confirmed attendee for the wedding. It turns out Dwayne is a close friend of the famous pair. He and Priyanka became good buds on the set of Baywatch. And he and Nick worked together when they filmed Jumanji.
Jack McBrayer
The 30 Rock was photographed arriving to a Mumbai airport en route to Nick and Priyanka's wedding.
Kelly Ripa
Kelly was one of the few guests invited to Priyanka's exclusive bridal shower at Tiffany's, so maybe she and hubby Mark Consuelos will be flying in to India for the nuptials.
Shania Twain & Nick Jonas
This may come as a surprise to some, but Nick and Shania share a strong bond. It all started when Nick sung his praises for the songstress, ultimately leading to onstage duets and concert. Hopefully Priyanka and Nick will get a chance to dance to her classic song "Man! I Feel Like a Woman."
Lupita Nyong'o
After the shining review Lupita gave Priyanka, it seems likely that she will be sitting front and center when Nick and PC say, "I Do." In a picture taken at Priyanka's bridal shower, Lupita shared her excitement over what is sure to be a "fly, fun, and totally extraordinary" marriage.
Demi Lovato
These two used to be good friends back in the day, when both stars were the biggest stars on Disney Channel. Demi also dated Joe for a short time after starring on Camp Rock. However, there's no word yet on whether or not Demi plans to join in the celebrations.
Prince Harry & Meghan Markle
Unfortunately, these two royals have yet to RSVP for their best friend's star-studded spectacular, but fingers crossed! It's important to note that several outlets have reported that the couple is not expected to attend.
Hilary Duff & Matthew Koma
Matthew and Priyanka go way back! The musician worked on some of Priyanka's most popular songs, like "In My City." Maybe him and Hilary will make a surprise appearance!
