"I’m going. I haven’t been told the location yet,” actor brother Stephen, 46, told The Post. “That’s about all I can say, because he [Alec] can still kick my butt.”

Meanwhile, Baldwin was expressing his love for Thomas on Twitter.

"But now abideth faith, hope, love, these three; and the greatest of these is love," Baldwin wrote on his Twitter account Saturday along with the words of an Emily Dickinson's poem.

Celebrities expected to attend were Baldwin's brother Stephen, Jimmy Fallon, the executive producer and the cast of "30 Rock," according to the Post and the Hollywood Reporter.

Baldwin and Thomas, a Spain-born yoga instructor and former ballroom dancer, got engaged early April after dating for one year. The couple reportedly met in 2011 while dining at an upscale vegan restaurant.

Baldwin has made headlines recently for having confrontations with photographers in two separate events.

On Friday, the actor reportedly got into a verbal confrontation with a photographer outside his New York City apartment, TMZ reported. He grabbed the photographer’s arm and yelled at him for allegedly harassing a neighbor.

On June 20, a photographer with the New York Daily News accused Baldwin of punching him in the face for taking photographs of him and Thomas. But Baldwin turned to Twitter to say the photographer almost hit him in the face with his camera.

Baldwin stars in the TV show "30 Rock" and also appears in the movies "Rock of Ages" and "To Rome with Love."

He was married to actress Kim Basinger from 1993 to 2002. They have a daughter together, Ireland who is 16 years old.
