Actress Angelina Jolie, who earlier this month filed for divorce from actor Brad Pitt, reportedly decided to split from him after she found photographs of singer Selena Gomez and some other women on his phone.

According to a source, Jolie had been really concerned about Pitt's "dalliances" with several women before she saw images of random girls on his phone, reports aceshowbiz.com.

"She found photos on his phone with everyone from flight attendants to biker babes at a motorcycle convention to Hollywood ingenues like Selena Gomez," the source told OK! Magazine, adding that the photographs led to a "blowout fight".

"She understands why women want to meet him, but why would he have photos with these random women?" the source added. 

The source also claimed that Jolie and Pitt's relationship got worse following the argument over the images. Not so long after that, she heard rumours that he had an affair with French actress Marion Cotillard, whom he was working with in "Allied".
