Cassie has fuelled rumours that secret boyfriend P. Diddy proposed when she was spotted last weekend with a large ring on her wedding finger.

The hip-hop mogul was said to have proposed to Cassie a few weeks ago and they added fuel to the fire when they began writing sweet nothings to each other on Twitter. The couple shared with their followers that they miss each other, while Cassie also wrote a few weeks ago: "I miss him."

While Diddy has been rumoured to be dating Hollywood actress Cameron Diaz, Cassie attended Rick Ross' 26th birthday party last weekend sporting a large rock on her finger. Diddy was also present at the star-studded shindig as he took on hosting duties for The Bawse.
