Ben Affleck, Jennifer Lopez stun in 1st red carpet appearance in 18 years

The couple dated in the early aughts but broke up in 2004.

It was already well-known that Bennifer 2.0 is in full swing, but Ben Affleck and Jennifer Lopez finally made their relationship red carpet official on Friday at the Venice Film Festival.

This marks the first time that the two stars have attended a red carpet event together since 2003, the year before they ended their engagement.

Affleck, 49, and Lopez, 52, attended a screening of "The Last Duel," which stars Affleck and his longtime pal Matt Damon. The pair also co-wrote the movie.

The drama, which is based on real events, sees Damon as a respected warrior in medieval France whose wife, played by Emmy winner Jodie Comer, has accused his best friend, played by Adam Driver, of sexual assault. Affleck co-stars as Count Pierre of Alençon, who plays a role in the case. It is directed by four-time Oscar nominee Ridley Scott.

The movie debuted at the festival, but hits theaters on these shores on Oct. 15.
