JLo, Casper Smart spotted with friends

Singer-actress Jennifer Lopez and her former boyfriend Casper Smart were seen dining and dancing with friends in Las Vegas.

Smart and Lopez, along with several friends, dined and danced at the MGM Grand's Hakkasan Las Vegas Restaurant and Nightclub on Friday, reports people.com.

Lopez, who wore a 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, said a source.

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" hitmaker 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 photographs with several fans and waved when clubgoers yelled her name.

The duo initially called it quits in June 2014, after dating for over two years.

They 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.
