and Catherine Zeta-Jones
are together again
on the red carpet.
The couple, who decided to step back and evaluate their marriage
last June, hit a red carpet event together for the first time together since their break on Tuesday for opening night of The Library
at The Public Theater in New York City.
The off-Broadway play, starring 17-year-old Chloë Moretz, concerns the aftermath of a school shooting and is directed by Steven Soderbergh, who directed both Douglas, 69, and Zeta-Jones, 44, in 2000's Traffic.
The couple looked relaxed and happily posed for photos, with Zeta-Jones in a plunging black dress and sporting blunt bangs.
The outing marks the latest sign of togetherness for the pair, who are parents to son Dylan,
13, and daughter Carys, 11, on Sunday, as they have been steadily working on mending
their 13-year marriage.
"It is so easy to just give up," a longtime family friend tells PEOPLE. "But they wanted to put in the work. I'm really happy for them."
