'Shahs of Sunset' Star -- My Nip Slip Selfie Was An Accident!!

"Shahs of Sunset" star Mercedes Javid says she never meant to post a photo showing her exposed boob and she blames the whole thing on a long flight.

Mercedes tells TMZ she took the pic while at a wedding last week and wanted to edit it the next day before a flight home with a sticker covering her nipple. However, she says before she could finish the edit job, the plane took off and she had to abandon her masterpiece.

Mercedes says somehow the pic still posted to her Instagram and Facebook and when she landed 8 hours later she got a ton of messages from friends about the pic so she quickly took it down.
