Was never `there` in relationship with Rob: Rita Ora

Los Angeles: Singer Rita Ora says she could not keep up with her relationship with Rob Kardashian.

Even though the news of separation between the couple emerged a few days back, the singer told Glamour magazine about her singlehood weeks before that, reports thesun.co.uk. "I`m not going out with Rob. We were close for a while, but it didn`t work because I was never there," Glamour magazine quoted Rita as saying. "I was like a ghost. I used to get so frustrated with myself and then wonder why I was angry, so I decided it was best to keep it friendly - especially at the moment, when there`s so much going on," she added. IANS
