Johnny Depp publicly claims to still be happily coupled up with Vanessa Paradis — his longtime partner and the mother of his two children.

However, In Touch can exclusively reveal that on February 27, Johnny was spotted making a hasty exit from an office building connected to Ashley’s apartment building “looking like he didn’t want to be seen,” a witness tells In Touch. In fact, an office worker confirms, “An e-mail went around to the employees saying Johnny Depp was using our building to try to avoid paparazzi.”

It turns out the star, 48, was secretly leaving 23-years younger Ashley’s loft after a sneak slumber party. Arriving in the afternoon of February 26, Johnny hunkered down in Ashley’s Tribeca digs until noon the next day — nearly 24 hours later. “It was quiet in her apartment, like it was just the two of them in there,” an insider recalls, and though no one outside can know what happened, “It didn’t seem like it was just a visit between friends.”

Whatever the twosome were up to during their overnighter, it certainly left Johnny exhausted. When the star finally left the next day, “he looked like he was out of it,” an onlooker said.
