TMZ has learned through sources close to Simmons that he is thinking about increasing his security detail because he believes that his ex-girlfriend, Tinashe, has been following him and his new girlfriend, Kylie Jenner.
While all three were at a West Hollywood nightclub last Thursday, Tinashe claimed that Simmons was texting her. Later it was learned that Tinashe was lying.
Tinashe and Simmons dated from March until late May.
