Jenny’s back on the block.
Surprise! Bronx-bornJennifer Lopez made an unannounced visit to the New York City borough where she grew up on Sunday to open the Center for a Healthy Childhood, a joint effort between her Lopez Family Foundation and the Montefiore Health System.
The pop star donated $250,000 for the project — and celebrated by appearing at Montefiore’s Community Health Fair along with her sister Lynda.
The two whipped up Lopez’s favorite drink, a spinach protein smoothie with sunflower butter. During the demonstration, the “I Luh Ya Papi” singer said her 6 1/2-year-old twins, Max and Emme, helped inspire her to serve her family a healthy breakfast.
“I knew the stuff that I was eating wasn’t giving me energy. I realized that after a while, and I was feeding this to my kids. Is this good for them?” she said. “So I was ready to try something different. …[This smoothie] tastes fresh, and you’re doing something good for yourself. It makes a huge difference.”
PEOPLE caught up Borges after the presentation, and he spilled the secret to creating J.Lo’s breakfast smoothie.
Combine all ingredients in a blender and blend until desired consistency is achieved.
