The Celebration of Life event was held at Faena Forum on Saturday night for JR Ridinger, a millionaire and co-founder of marketing firm Market America. The 63-year-olde died of a pulmonary embolism on vacation while sailing on his yacht in Croatia last month.

Kim arrived in a black Balenciaga dress, with a matching glitter purse and large "B" earrings from the fashion house. She was accompanied by her BFF Jonathan Cheban, also a staple on Keeping Up With The Kardashians.

The reality star traded pleasantries with Jennifer Lopez and Ben Affleck, who showed a united front despite whispers of their new marriage having already hit rocky territory. The two were also dressed in black – JLo in a long gown and Ben in a suit – and accompanied by Jen's child Emme.

"Last night we celebrated JR’s life and even through all the deep pain and endless tears of the past month we got to smile, reminisce and even #DanceAgain," Jennifer wrote in a social media post sharing photos from the event. "He would’ve loved it!!"

Multiple videos across Instagram stories of those in attendance showed the Jenny From The Block star taking to the stage to sing along with Alicia Keys on hits like No One and Empire State of Mind. Others took the mic to toast Ridinger and pay respects to his wife and company co-founder, Loren. Their multimillion dollar marketing company sponsored many music and sporting events, and the two rubbed elbows with many famous faces at events and charity functions.

Later in the evening, Kim was pictured chatting with Jamie Foxx, while other notable names in attendance were Emilio and Gloria Estefan, Fat Joe, Larsa Pippen, DJ Khaled, and Ja Rule.

The latter two sang versions of their songs All I Do Is Win and I'm Real (Remix), accompanied by his duet partner JLo, of course.
