Joe Jonas & Sophie Turner Pack On The PDA At US Open Date Night

It’s love – on and off the tennis court!

Joe Jonas and Sophie Turner only had eyes for each other at the US Open on Friday night, sharing sweet glances and kisses as Venus and Serena Williams competed in the third round of the annual tournament.

The DNCE frontman and the “Game of Thrones” beauty both dressed to the nines for their night in New York City. Joe opted for a buttoned-up, monochromatic ensemble, while Sophie tried out menswear in green windowpane suit and white tennis shoes.

Throughout the match, the engaged couple kept the affection going – intertwining their fingers, snapping photos, whispering in each other’s ears – and cracking jokes! At one point, Sophie playfully stuffed a seat cushion underneath her blazer, giving off the appearance of a baby bump. The 22-year-old grinned and puffed out her faux belly, and Joe couldn’t help but crack a smile as he sipped a drink beside her.

Sophie and Joe announced their engagement last October in a pair of Instagram photos, and they seem to be making the most of their first summer as a to-be-wed couple. Over the past few months, the lovebirds have traveled all over the world – double dating with Nick Jonas and Priyanka Chopra in London, getting coordinating tattoos in memory of their grandfathers in New York City and partying in Miami for Joe’s 29th birthday.
