The stunning singer was a vision in white at an event with Hoda Kotb to celebrate the launch of her new book "True Love," on Thursday in New York City.
Rocking a white lace blouse and curve-hugging high-waisted white slacks, the 45-year-old looked sexy yet stylish for her public appearance.
Lopez finished her look styling her long locks straight and sported natural makeup for the event.
The "On The Floor" singer has been making headlines this week for her new memoir, which details her relationships with exes Ben Affleck and Marc Anthony.
Coincidentally, Anthony announced his engagement to his on-again-off-again girlfriend Shannon De Lima earlier this week, which marked the start of the "American Idol" star's promotional book tour.
But it seems like there's no bad blood between the famous exes who share two adorable children together, Emme and Max.
