Jennifer Lopez is donating $1 million to hurricane relief efforts in Puerto Rico

Speaking during a press conference with New York Governor Andrew Cuomo, she said first in Spanish, and then in English: "Alex Rodriguez and I, who are both New Yorkers, are using all our resources and relationships in entertainment, sports and business to garner support for Puerto Rico and the Caribbean."

The 'On the Floor' hitmaker revealed the New York Yankees and Major League Baseball have pledged to help in a major way, while she and her ex-husband Marc Anthony - the father of her nine-year-old twins Max and Emme - have been working to mobilise over 30 athletes and artists to quickly get aid to Mexico and the Caribbean.

Dallas Mavericks owner Mark Cuban and player J.J. Barea have been working with Jennifer and have two planes of help and generators ready to fly to Puerto Rico.

She added: "We are working day and night to identify the needs."

During the press conference, the 'Shades of Blue' star admitted she still hasn't heard from her family and she is "concerned", for both her own loved ones and "everyone on the island".

Jennifer previously used Instagram to urge her fans to help the aid efforts in Puerto Rico.

She said: "What's on my mind is what's going on in Puerto Rico. The devastation is beyond belief... Me and my cousin still haven't been able to hear from our families over there."

The brunette beauty - who has helped fund medical facilities in Puerto through her Lopez Family Foundation - asked her fans to donate and "help rebuild" the island.

She continued: "Today, Puerto Rico needs our help. I urge you to support and donate to the efforts of the First Lady of Puerto Rico, Beatriz Areizaga... Together we can help rebuild our island, and the Caribbean."
