J.Lo, 54, attended the star-studded evening to support the actor, who was nominated alongside pal Matt Damon for their movie “Air.”
While the co-stars didn’t take home any wins, they presented the award for Best Director in a Motion Picture to “Oppenheimer” director Christopher Nolan.
Earlier in the evening, Lopez gushed about how proud she was of the “Argo” actor and his close pal Damon, who was also nominated for a Best Actor trophy.
“I’m so glad to be here tonight because he’s nominated and I’m so proud of him and I love the movie,” Lopez told Variety during her red carpet appearance prior to the award show.
“I really do think it was one of the best movies of the year so I’m happy for him and Matt, who are both nominated,” she added.
Lopez stunned in a Barbie-esque pink gown with a rosette cape by Nicole + Felicia Couture and was dripping in diamond jewelry by Maison Boucheron.
Since tying the knot in July 2022, Lopez and Affleck have continued to make headlines for their contrasting moods in paparazzi photos.
