Sofia Richie isn’t letting the drama surrounding new flame Justin Bieber and his now-deactivated Instagram account get to her.

In videos shared to her Snapchat story on Tuesday, the 17-year-old model laughed off reports that she has weighed in on Beiber’s public feuds with ex-girlfriends Selena Gomez and Hailey Baldwin.

“I don’t even have a Twitter account,” she said, while reading a post about the controversy.

“Whaaat?” she laughed to a friend, who shrugged the news report off.

Whether or not Richie and Bieber last for the long-haul, one thing appears to be true: she likes his music.

Richie and pal Chloe Bartoli sang along on Snapchat to Bieber’s new track with DJ Snake – “Let Me Love You” – while out on a “day of fun.”

If she needs it, Bartoli could help give Richie some advice about navigating a high-profile romance. The 26-year-old stylist has been previously linked with Scott Disick and Orlando Bloom.

Bieber and Richie’s relationship has been heating up over the last couple weeks, but one source close the 22-year-old singer exclusively tells PEOPLE they won’t be together forever.

“Sofia and Justin are basically on a love-fest right now,” the insider explains, “but it’s virtually impossible where he’s at in his life and career for anything to last with these girls.”

Before spending time together in Japan – where Bieber was due to perform as part of his Purpose tour – the pair hung out in Laguna Beach and at his Toluca Lake home, says another insider.

“These girls all go crazy for him, but he’s not settling down,” says the source, who adds that the budding couple have “run in the same circle for years.”
