Smart and Lopez, along with several friends, dined and danced at the MGM Grand’s Hakkasan Las Vegas Restaurant and Nightclub on Friday. Lopez, who wore a sexy white jumpsuit and carried a leopard Valentino bag, arrived for dinner with friends at the restaurant, and “cozied up” at their Private Dining Room table, a source says. After dinner, Lopez, 45, made a quick change for a night of dancing. Clad in a crop top, leggings, sneakers and a bucket hat, the “Feel The Light” songstress enjoyed the music from her VIP table on the nightclub’s fourth floor main stage. The source said that Lopez, “in good spirits,” posed for photos with several fans and waved when clubgoers yelled her name. The couple initially called it quits in June 2014, after dating for over two years. The duo recently vacationed together on April 4, celebrating Smart’s birthday and the Easter holiday in Ensenada, Mexico. Smart later shared a video on Instagram, biking along the beach with Lopez back in California. Lopez, who is 18 years older than her former flame, told Andy Cohen that she’s open to dating other younger men on Watch What Happens Live back in January. Are Jennifer Lopez and Casper Back Together?
