According to BET, the low-key couple may have gotten engaged earlier this year, but decided to keep the news a secret. Milian and Prince have been dating since September 2010.
If the rumors are in fact true, this would be the second time the 31-year-old singer turned actress ties the knot. Milian was briefly married to music producer The-Dream in 2009. The former couple has one daughter, Violet.
News about Milian's engagement comes amid rumors that she will be joining the cast of "Dancing With The Stars" for the show's upcoming Season 17. Reps for the show have refused to comment on rumors claiming the official cast will be announced on September 4 on ABC's "Good Morning America."
