The wedding of Boston Celtics guard Payton Pritchard was performed over the weekend by a special guest: six-time NBA All-Star Blake Griffin.

The former LA Clippers star presided over the ceremony between Pritchard and YouTuber Emma MacDonald in Cape Cod, Massachusetts. Griffin was Pritchard’s teammate on the Celtics during the 2022-23 season, Griffin’s final year in the NBA.

MacDonald told Elle that Griffin was there from the beginning, offering advice to Pritchard when the two first started talking. He was even the third wheel on one of their dates.

He performed the wedding ceremony last Saturday.

Celtics star Jaylen Brown posted a short clip of Griffin joking about his impersonation of Pritchard during the ceremony.

“We chose him because we knew he would keep the ceremony nice and relaxed and he did a fantastic job!” MacDonald wrote on Instagram on Wednesday. “People were so excited and so were we. It was incredibly special to have one of our friends marry us!”

Pritchard and MacDonald began dating in 2021 and got engaged in July 2023.

Celtics governor Wyc Grousbeck, head coach Joe Mazzulla and Pritchard’s teammates Oshae Brissett, Sam Hauser and Xavier Tillman were in attendance.

Pritchard averaged 6.4 points, 2.1 assists and 1.9 rebounds in 18.7 minutes per game in last year’s postseason. He became famous for his mid-court shot to end the first half in Game 5 of the NBA Finals, the longest shot in the NBA Finals in the last 25 years.
