A source told People.com: "All I know about the ring is that it's big".
Blonde bombshell Ariana was spotted wearing a ring at iHeartRadio and 102.7 KISSFM's Wango Tango concert in Los Angeles earlier this month. Since then, they have been posting videos and pictures together, and leaving adorable comments on each other's posts.
According to a source who broke the news to People, the engagement is recent, and they are just two people who have found love quickly.
A second source confirmed that there are no immediate wedding plans by saying, "They are a flawless fit".
The Florida singer also told her friend Camila Cabello - who often calls her "wife" - that they "need to talk". They're already reportedly telling people they're getting married! "They've been very public with their relationship on social media, and they are very in love". She later described that relationship as "toxic" after a Twitter user wrote it was "heartbreaking" that Miller got a DUI shortly after their breakup.More news: McGregor Confirms He Was Set For UFC 224 Card
