Inside Jennifer Lopez & Alex Rodriguez's Engagement Party

Leah, 49, posted a gorgeous photo with her pal Jennifer, 50, during what looked to be an elegant extravaganza. “#reunitedanditfeelsogood,” she captioned the snap.

Others in attendance included Leah’s husband and former King of Queens costar Angelo Pagan and Jennifer’s longtime manager Benny Medina.

Angelo, 51, shared an Instagram video on Saturday, September 28, of him singing The Four Tops song “Ain’t No Woman (Like the One I Got)” with Leah and Benny, 61, during the party.

Lyricist and singer Carole Bayer Sager shared an Instagram pic with Leah and Jennifer while there. “With @jlo and @leahremini It happened last night!” she wrote as the caption.

Jennifer and Alex’s engagement party took place seven months after he got down on one knee and proposed to her. "She said yes ♥️," he wrote on Instagram, alongside a photo of the “If You Had My Love” singer’s hand with a massive sparkler on her ring finger. She posted the same photo, adding, "♥️♥️♥️♥️♥️♥️♥️♥️."

The dancer and baseball legend dated for two years, beginning in February 2017, before Alex, 44, popped the question. Their upcoming nuptials will be her fourth time down the aisle, his second.

The Hustlers star revealed wedding secrets with Entertainment Tonight earlier this month, saying “We're talking about it, but we don't have any firm plans... and we're talking about a lot of places to get married in, but I don't know yet," she said, adding that they haven't even picked a time to tie the knot. "We can't narrow it down yet.”

One thing that’s for certain is that her son Max (who she shares with ex-husband Marc Anthony along with daughter Emme) will be walking her down the aisle when the big day happens.

Alex has two children, daughters Natasha and Ella, with ex-wife Cynthia Scurtis. They divorced in 2008 after six years of marriage.
