On Wednesday she became the UN Foundation's first Global Advocate For Girls And Women.

And Jennifer Lopez was pressed into service straight away as a speaker at the Foundation's Gender Equality Dinner at The Four Seasons Restaurant in Manhattan, New York on Friday.

The 46-year-old actress-singer, who looked lovely in a Fifties-inspired pastel ensemble, made it a date night and brought along her younger boyfriend Casper Smart, 28.

Jennifer was due to talk up the business case for investing in girls, women and gender equality at the high-level event.

J-Lo was beautifully dressed for the big bash in a shimmering pale gold silk blouse and a full, pale pink skirt made of layers of chiffon, which she paired with salmon pink suede high heels.

She styled her brunette tresses in an elegant updo, giving a clear view of her perfectly made up face.

Her on-again beau Casper was suited up in a blue two-piece with a white shirt covered in tiny black spots.
