You could see right through Jennifer Lopez’s dress, and right through A-Rod’s heart in this romantic picture of the two! Read her boyfriend’s message that wins him even more brownie points. Jennifer Lopez, 49, makes boyfriend Alex Rodriguez, 43, “feel like a kid again,” as he said in his Instagram post on Dec. 18! And we can see why — pictured sitting by him on a swing set was J.Lo, who looks like she’s approaching 30 rather than 50. The “El Anillo” singer put her curves on full display through a completely sheer dress…cleavage and all! A-Rod kept up with his girlfriend’s glamour in a dress shirt and tie, but they looked anything but stuffy in the formal clothes, as both wore big grins. A-Rod’s post is a behind-the-scenes look at their photo shoot for People, which published their cover story last week! The smiles you see below are far from forced. “We love each other and we love our life together,” J.Lo gushed in the cover story. “The exciting part of our love is that we’re both very aware of how lucky we are to have found each other.” She added that her and A-Rod’s kids, who come from separate marriages, have also become close as a result! A-Rod — who shares daughters Natasha, 14, and Ella, 10, with ex-wife Cynthia Scurtis — even added that the kids are all “best friends,” while J.Lo elaborated, “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.’” J-Lo shares 10-year-old twins Emme and Max with ex-husband Marc Anthony. J.Lo and A-Rod, who have been dating for two years, were just as loved up on the streets of Beverly Hills on Dec. 17! The couple walked hand in hand, reportedly on their way to Craig’s, and were all smiles yet again. We’re happy to see J.Lo finally get to kick back in a pair of yoga pants, which she wore for the casual date night, after attending the premiere of Second Act on Dec. 12! Of course, A-Rod didn’t miss the premiere of his love’s new film, sticking by her side as she sauntered down the carpet in a ginormous pink dress with a train that spanned the width of several paparazzi’s feet. Look at those sweet smiles! And, sheesh — look at that bod. The Latin songstress makes a strong case for see-through outfits, even one week away from Christmas.
