Nicki Minaj posted a pic of some serious bling on Instagram last night (her caption simply read: 💛💎💍😍😍😍😍😍🙌🙈 💛), and the 32-year-old entertainer is reportedly engaged to rapper Meek Mill, who she's been dating for about 3 months.

"Both Meek and Nicki have been spending amazing quality time together lately and have gotten extremely close these past few months," an insider tells E! Online, confirming the engagement news. "It may seem like it all is happening very quickly but Nicki and Meek are in this 100. They truly love each other." The site adds that the ring is about 15 carats and estimated the cost to be a cool $500,000.

On Tuesday Minaj posted a photo of the duo in Miami, and when fans noticed that the "Super Bass" singer was rocking a diamond ring, she responded and commented, "I'll post it later." While Minaj's new tune (which features Meek Mill) is titled “Buy A Heart," we can't imagine she'd punk us just in an attempt to drum up some publicity. Hmm, or would she?

Last year Minaj split from her boyfriend of 11 years Safaree Samuels, and at the time there were reports that she chased him out of her home with a baseball bat following an argument. A few months later Safaree chatted with The Breakfast Club on Power 105.1 and said, "Everyone around her works for her, you know? And it got to the point where I was being treated like an employee, instead of like her man." Nicki may be a babe, but it sounds like Meek is in for a wild ride!
