The singer-actress and Prince have kept their relationship under the radar since 2010, but Life & Style is now reporting that the couple has been engaged for a few months. A source told the magazine that she is "over-the-moon happy" and "truly enjoys their active relationship."
In April, Milian was seen sporting a diamond ring, which prompted engagement rumors too.
Rumors are also swirling that she will be joining the next season of "Dancing With the Stars" though she has yet to confirm.
HuffPost Celebrity has reached out to the singer's reps for comment but did not receive an immediate response.
