Jennifer Lopez looks sensational in a sheer silver dress as she shares a swing with her beau

Playful and in love, Jennifer Lopez and Alex Rodriguez share a double swing and a joyous grin.

Alex Rodriguez posted a photo on Instagram that has fans sighing in pure envy. The 43-year-old former professional baseball has plenty to smile about, in the magic moment captured by the photo, and in every other moment of his life.

Rodriguez has been in a relationship with Jennifer Lopez since 2017, and the couple is as carefree and joyfully in love as a couple of starry-eyed kids. Literally.

"You make me feel like a kid again"

YOU MAKE ME FEEL SO YOUNG

In the photo, Rodriguez and Lopez are sharing a double swing and smiling as broadly as two delighted children in a playground.

The two are obviously dressed up for some very grown-up event. Rodriguez is wearing two pieces of a three-piece suit - pants and a waistcoat - over a pale blue shirt and an elegant check tie.

He recently posted a photo of a chalkboard set up above the mantle at chez Lopez/Rodriguez with a list of who's been naughty...and nice.

BAREFOOT IN THE PARK WITH ALEX

Lopez is wearing a dazzling long, sheer, silvery dress that breaths sensual elegance - and no shoes. The singer/ actress' long blond tresses are loose and tousled by the wind, and her best accessory is her delighted smile.

GETTING BACK IN SANTA'S GOOD BOOKS

Rodriguez captioned the photo, "You make me feel like a kid again," and he looks like a very naughty boy.

On the nice list are Lopez, her daughter Emme, 10, and Rodriguez's daughter Ella, also 10. On Santa's bad books, are Rodriguez, Lopez' son Max, 10, and Rodriguez's older daughter Natasha, 14. Rodriguez captioned his post:

"What do I need to do to make it on the nice list?"

We would suggest a pretty box with an engagement ring slipped in under the tree for a Christmas surprise, given on his knees, and with that cheeky naughty boy smile.
