She was celebrating her 46th birthday - and like any self-respecting pop star, Jennifer Lopez made sure she was going to be noticed.

The American singer and actress chose a particularly revealing outfit for her party at a New York nightspot.

Her custom-made cut-away black dress by designer Bao Tranchi featured see-through panels and served to show off her famous curves. Lopez, who performs under the name J-Lo, was joined by a host of stars and her 28-year-old boyfriend, dancer Casper Smart, at celebrity club 1Oak on Friday.

Earlier she had commemorated her special day by sharing on the internet a picture of herself celebrating her birthday when she was a toddler. The photo showed her in a crimson dress, smiling and posing in front of a white birthday cake covered with pink frosting flowers.

Lopez began her career with a small role in 1986 film My Little Girl before going on to release her first album in 1999. She has since sold 55 million records and amassed a fortune of more than NZ$100 million.

She has been married three times and has seven-year-old twins by her third husband, singer Marc Anthony.
