Jennifer Lopez's Maribel Charity Press Conference

She recently opened up to her audience with a tearful performance in Montville, Conn, and just days later Jennifer Lopez stepped out for a charity press conference in Los Angeles, CA on Tuesday (October 25).

The “On the Floor” songstress looked stunning in a sky blue, criss-cross Lisa Ho gown with her long locks twisted into a high bun and accessorized with hoop earrings.

With her younger sister, Lynda, in tow, the siblings stepped out to support the Maribel Foundation, a non-profit organization formed by Jen back in 2009.

Her foundation recently announced its partnership with Samsung and Best Buy, who have pledged to donate up to $500,000 to the cause from the sales of select Samsung products.
