Tough day at work! For maybe the first time ever, Jennifer Lopez didn't just have all eyes on her. During a taping for her new music video, the singer was surrounded by sweaty, shirtless men on a luxury yacht in Miami, Fla., on Wednesday, Feb. 12.

In photos, Lopez, 44, simply glowed while wearing a skin-tight long-sleeve cut-out top, and white hot pants that accentuated her gorgeous curves, long legs, and her famous derriere. With a sleek sectioned ponytail, she wore reflective gold sunglasses reminiscent of her "Jenny from the Block" days. The "We Are One (Ole Ola)" World Cup music video also featured several (shirtless! speedo-clad!) hot men that surrounded the singer on board of the yacht.

Earlier in the week, Lopez let her hair down while filming on Feb. 12. She rocked hot pants once again with a graphic printed top with gold jewelry, red lipstick, and Casadei's lobster fluon pumps. She similarly stepped it up the day before in a colorful skirt and fishnet stockings, a white crop top, and a chunky gold necklace.

The American Idol judge kept busy in the Miami heat, but managed some downtime with dancer-choreographer boyfriend Casper Smart. The couple were also joined Emme and Max, the diva's 5-year-old twins with ex Marc Anthony.

On Thursday, Feb. 12, the adorable tots were photographed walking onto the dock while holding hands with bodyguards to see their famous mom. When not filming, Lopez could also be seen dressed down in sweatpants and an off-the-shoulder white t-shirt. She kept close to her 26-year-old beau as he too dressed comfortably in shorts, a white t-shirt and a New York Yankees baseball cap.
