Call him the officiator-in-chief: Former President Bill Clinton will preside at the wedding of New York Rep. Anthony Weiner to Huma Abedin, Secretary of State Hillary Rodham Clinton’s longtime aide.

That’s according to people familiar with the ceremony. They spoke on condition of anonymity because they were not authorized to discuss it, and aides to Weiner and the former president declined to comment.

Weiner, 45, and Abedin, 34, are to be married Saturday at the Oheka Castle in Huntington, on Long Island.

The couple have been dating for about two years and announced their engagement last summer.

Weiner is Jewish, while Abedin, who grew up in Saudi Arabia, is Muslim.

The Clintons are in the midst of a busy wedding season. Their daughter Chelsea plans to tie the knot with investment banker Marc Mezvinsky in Rhinebeck, New York July 31.
