The 33-year-old singer discussed the 32-year-old rapper in an interview with Big Boy on Real 92.3 this week. Milian didn't object when the DJ referred to Lil Wayne as her boyfriend, and accidentally confessed her love for the star.
"He's the sweetest, I love him," she admitted before explaining the diamond ring on her left hand. "This is not an engagement [ring]. It was just a sweet little gift, a nice gesture. I just said it... I do [love Lil Wayne]."
Milian and Lil Wayne have been subject to dating rumors for months, and were spotted holding hands on the set of new Fox pilot Grandpa in March. The singer previously told Latina magazine she and the rapper share "a very special relationship."
Milian married and separated from musician The-Dream in 2009. The pair welcomed their first child, daughter Violet Madison, in February 2010, and finalized their divorce in October 2011. Lil Wayne has four children by four former partners.
