It's only been a little more than a week since news broke that Aaron Rodgers and Olivia Munn have called it quits, but that didn't keep the Green Bay Packers quarterback from celebrating love by serving as a groomsman at his teammate Randall Cobb's wedding on Saturday.

Cobb tied the knot with his girlfriend, attorney Aiyda Ghahramani, at a large ceremony at the Pierre in New York City. The Packers wide receiver and his bride celebrated with hundreds of guests, including Rodgers and fellow teammate Jordy Nelson.

The couple spoke with The Knot after exchanging vows, and Cobb said he was excited to "have the people we love most, together, in the same room to celebrate our union."

Cobb and Ghahramani met in 2011 at an EA Sports event at Manhattan where they "had an instant connection and became fast friends," the bride shared.

The bride's brother, actor Ariya Ghahramani, shared a pic of himself and his fellow groomsman the night before the actual ceremony.

"Groomsmening for my sisters rehearsal for her wedding," he captioned the group shot.

Rodgers was all smiles in the photos shared from the rehearsal dinner, despite his split from Munn last month, after three years of dating.

Last week, a source told ET that NFL pro and the Office Christmas Party actress broke up after they "grew apart over time," adding, "They tried to make it work but just couldn't." Check out the video below for more.
