Rumors are circulating that Johnny Depp had a one night stand with Ashley Olsen on February 27.

In Touch reported that a witness saw Depp leaving the office building connected to Olsen's apartment looking like he didn't want to be seen the morning of February 28.

An office worker confirmed the allegations, telling Star that  an email went around to the employees saying Johnny Depp was using our building to try and avoid paparazzi.

In Touch said that Depp and Olsen had a sneak slumber party that left Johnny looking exhausted.

He looked like he was out of it, said an insider to In Touch.

Depp arrived at Olsen's Tribeca apartment in the afternoon on February 26 and left the next day at noon -- almost 24 hours later.  

It was quiet in her apartment, like it was just the two of them in them, a source told In Touch. It didn't seem like it was just a visit between friends.

Olsen is 23 years younger than the 'Pirates of the Caribbean' star.

Depp has been with Vanessa Paradis for 14 years. The couple has two children, Lily-Rose, 12 and Jack, 9.
