According to HollywoodLife.com, the "Same Old Love" pop star wants to keep her life "as drama-free as possible" even if it means staying away from the Biebs.
Apparently, the "Purpose" singer has been trying to get the One Direction cutie to spill details on his involvement with Sel.
"Justin wants to see his so-called friend in person and confront him," a source told the site. "He texted him a couple of messages but Niall isn't engaging, per Selena's instructions."
"She begged Niall not to get into it with Justin and to just avoid him for the time being. Niall doesn't like drama anyway so he's just taking Selena's advice."
Selena and Niall sparked dating rumors last month. They were seen having dinner with friends, and the rumored couple was also spotted kissing at Jenna Dewan-Tatum's 35th birthday party at Bootsy Bellows in Los Angeles.
