Drake was performing at Coachella when Nicki jumped onstage where he began heaping praise on her, then congratulated her. He wasn't specific about her achievement, but when the 2 hugged, the ring on her finger is unmistakable.
Nicki posted a pic of the ring on her finger last week, but didn't really say anything about it. Meek posted, "I wish every night could feel like last night."
Easy to read between the lines.
