“Work hard, play hard” is the motto that many successful moguls live by, and it looks like Jennifer Lopez and her beau Alex Rodriguez are doing much of the latter. Their Instagram photos show that the couple is on a luxury, tropical vacation, and Jenny from the Block has no problem rocking sweats or a teeny weeny green bikini on a private beach. Pushing out her backside in a selfie, Lopez captioned the photo “beach bums.” That’s a #10DayChallenge booty right there.

Over on A-Rod’s Instagram page, he shares a clip of Lopez winding her hips and showing off her backside and dance skills with the caption, “Heading into the weekend like: 🌴.” Fans are still waiting for the couple of two years to tie the knot, but they did recently talk about what it’s been like blending their families together. “Kids are so beautiful and open to love and new friends,” Lopez told People. “I was so loving to his kids and he was so loving and accepting of mine, and they embraced each other right away. [It was] ‘I get a new bonus brother and sisters to hang out with all the time and it’s nice.”

“Our kids have become best friends and that keeps us both grounded and appreciative. We couldn’t have asked for anything better than the four of them getting along as they do,” Rodriguez added. “We love each other and we love our life together,” Lopez continued. “The exciting part of our love is that we’re both very aware of how lucky we are to have found each other.”
