US Weekly reported that the couple, both 24, attended Robert Pattinson's birthday party in Los Angeles over the weekend and were telling people they were engaged. They are not rushing to get married. "They've been very public with their relationship on social media, and they are very in love". "Their friends are really excited and supportive". "It's nothing they've been hiding", a source close to the couple told People. Despite their relationship just being a few weeks old, Davidson made things permanent by getting two tattoos in honor of the singer earlier this month.
So far Davidson has yet to respond, but we're sure he's just as over the moon as Grande. Meanwhile, Davidson recently broke up with his girlfriend of two years, Cazzie David, after almost two years of dating.
