“Maks and Peta’s wedding will be something to remember! It will be a huge wedding that will span the course of a three day weekend,” the source revealed.

The wedding will take place on Saturday, July 8, at Oheka Castle, one of Long Island’s most exclusive venues. Guests will be treated to a Shabbat dinner the night before and a Sunday brunch the day after the wedding.

The source also explained that Peta is a bit nervous that Shai might cry through most of the ceremony, but is excited that he’ll be part of the festivities on such a special day.

Maks’cousin and former Dancing with the Stars troupe dancer, Nicole Volynets, is helping plan and style the wedding. According to the source, Peta will have two wedding dresses.

A second source tells ET that a few of the couple's DWTS friends will be attending the wedding, including Sharna Burgess and Tony Dovolani, who are both in the bridal party. Keo Motsepe, Amber Rose, Nyle DiMarco, Nick Viall and Vanessa Grimaldi are also expected to attend.

Val Chmerkovskiy will definitely be in attendance to lend his support to his big brother. But, it’s unclear on whether or not the DWTS pro will be showing up solo or with a date. The 31-year-old dancer appears to have rekindled his romantic relationship with former girlfriend, Jenna Johnson. According to the source, Johnson will be filming So You Think You Can Dance in July, so it’s not yet known if she’ll be attending the festivities.
