Jennifer Lopez and Alex Rodriguez dazzled at a friend's wedding over the weekend. The 48-year-old singer and 42-year-old retired MLB star dressed up Sunday to attend Sophie Lasry's wedding to Alexander Swieca in New York. Lasry is the daughter of hedge fund manager Marc Lasry. Lopez stunned in a teal dress with a plunging neckline and gold platform sandals, while Rodriguez looked dapper in a black tuxedo. E! News reported Lasry's wedding was the first wedding Lopez and Rodriguez attended as a couple. "Just another Sunday night," Lopez captioned a photo on Instagram of herself and Rodriguez on the way to the ceremony. "Date night in the city #Lasrywedding," Rodriguez added to a picture on his own account. Lopez spent Saturday with her children, Emme and Max, Rodriguez's daughters, Natasha and Ella, and her mom, Guadalupe Rodriguez. She shared a photo with her mom, writing, "Me and my beautiful mommy." People reported Lopez brought her mom and the kids to watch a New York Mets game at Citi Field. Rodriguez, who played for the New York Yankees, was covering the game for Fox Sports. Lopez and Rodriguez were first linked in March, and confirmed their relationship the same month. The singer couldn't help but gush about Rodriguez on his birthday in July, saying he makes her heart "skip a beat every time he walks in the room."
