"Love Don't Cost A Thing" hit maker Jennifer Lopez celebrated her birthday on July 25, Saturday, at 1OAK in Soutampton, New York.
Although the singer has turned 46, she looked ageless and youthful in her super revealing dress. The singer was seen flaunting a black sheer cutout dress by little known Los Angeles-based designer Bao Tranchi.
The dress left little imagination with its deep side cut outs and strategically-placed panels. The sheer texture covering the singer's derriere clearly suggested that the "Booty" hit maker has decided to go commando on her big day.
The singer arrived at the party hand-in-hand with her on-and-off boyfriend Casper Smart. The pair remained together most of the evening while the 28-year-old was also seen getting a little protective for the beauty.
"He had his arm around her, and they were tight all night," Us Weekly quoted a source, who further told that Smart jumped to the singer's rescue when he found her surrounded by the fans who were incessantly trying to take photos with her.
Lopez's boyfriend reportedly told the fans to back off a little and give some space to the singer, so that she can dance and have a good time, after which the mother-of-two reportedly danced all night and had a good time.
The party was attended by many of the singer's celeb-friends, including Thalia, French Montana, Natasha Bedingfield and rapper Fat Joe, Business Standard reported. Her close friend and longtime manager, Benny Medina, took the occasion to honor her friend by giving her a touching toast and a large customized cake.
Meanwhile, Lopez is gearing up for her NBC's 13-episode television drama, "Shades Of Blue," in which she will portray a single mother and a detective, who goes undercover to investigate her own squad. The show is expected to air by late 2015.
