Engagement rumors swirled after Diddy posted a photo of a diamond ring on Instagram over the weekend. He wrote, "Baby do you like it? I just want to get you wat you Like! I just wanna Mk you smile!"
His publicist has since confirmed the couple is not tying the knot and the ring was simply a present.
Combs and Cassie sparked engagement rumors in April 2012 after she revealed a picture of her new manicure while sporting a large gem on her ring finger.
Meanwhile, "Downton Abbey" star Hugh Bonneville is urging TV bosses to give Combs a role after he previously joked about joining the cast.
Last year, the rapper announced he had landed a part in the hit British drama, but it later emerged he had filmed an online spoof for FunnyOrDie.com.
