At the premiere of Showtime’s The Affair in New York City on Monday (Oct. 6), the loved-up couple held hands as they posed for photographs, looking impossibly smitten.
Joshua sported a dashingly handsome Ermenegildo Zegna suit with a fitted black T-shirt, while Diane wowed in a bombshell black-and-white frock by Michael van der Ham.
The 36-year-old Dawson’s Creek alum stars alongside Maura Tierney, Dominic West and Ruth Wilson in the upcoming drama.
After the glamorous event, Diane got up close and personal with her beloved, riding on his lap in the passenger seat as the duo departed.
Monday proved to be a big day for Joshua, as he was reunited with his Cruel Intentions co-star, Ryan Phillippe, on The Today Show.

On the program, the Mighty Ducks actor noted, “Randomly, one of your other guests today, I made a movie with in 1998. We were both kids and now I just met his son, who is closing in on 10. He told me his daughter is in high school now.”
The Affair premieres on Showtime on Sunday, Oct. 12.
