The on-again couple was spotted in Tokyo today with the actor's two children—14-year-old Lily-Rose and 11-year-old Jack—in tow.
The outing marks the first time Amber has been seen with Johnny's kids since the twosome first started dating last year.
The blond beauty looked travel chic in a white maxi dress and trendy shades with her hair swept up in a ponytail. She placed her arm around Jack and walked with Lily-Rose as she led the way through the busy terminal.
Of course, the 50-year-old actor appeared fashionable as ever, rocking an edgy fedora, purple-tinted shades and hot pink nail polish (natch).
Depp is currently in the Japan promoting his latest flick The Lone Ranger (the film is currently in theaters in the U.S.), and the Dark Shadows star seemingly turned his most recent promotional appearance into a family affair.
This isn't the first time Heard has accompanied Depp on the Lone Ranger press rounds—the pair was recently spotted showing off some subtle PDA after a screening in Moscow.
The notoriously private couple met on the set of The Rum Diary back in 2010 (Heard played Depp's love interest in the film), but they were not romantically linked until Depp split with his partner of 14 years (and the mother of his two children) Vanessa Paradis .
In June, the Pirates of the Caribbean star opened up about the pair's painful split, admitting he and Vanessa have tried to maintain an amicable relationship because of their kids.
"The last couple years have been a bit bumpy," Depp told Rolling Stone magazine. "At times, certainly unpleasant, but that's the nature of breakups, I guess, especially when there are kiddies involved."
He added: "So for whatever reason that ceases, it doesn't stop the fact that you care for that person, and they're the mother of your kids, and you'll always know each other, and you're always gonna be in each other's lives because of those kids. You might as well make the best of it."
While Depp's personal life is seemingly going well, his professional life has recently been hit with a box office blow after The Lone Ranger bombed in theaters.
Despite the small set-back, Depp has landed a leading role in the movie adaptation of Stephen Sondheim's Tony award winning musical Into the Woods, and he's also reportedly in talks for an Alice and Wonderland sequel.
