The 28-year-old pop star told ELLE UK in a candid interview that she sent a text to Stewart saying that she would never disrespect the âTwilight' actress because she is not that type of a person, the New York Post reported.
The âFirework' singer jokingly added that she was just trying to be a friend to Pattinson but it is unfortunate that she had a set of tits.
