50 Cent Shuts Down Engagement Rumors

Over the weekend rapper 50 Cent's longtime girlfriend Cuban Link sparked engagement rumors after flaunting a huge diamond on her ring finger [click here if you missed that]. 

Not so fast...

From TMZ 

A rep for 50 Cent tells TMZ Hip Hop ... the ring is not an engagement ring, but the couple IS very much together.

Cuban certainly helped stir the rumor pot with her IG post showing herself backstage watching her man with a Summer Walker love ballad playing -- plus, her caption had white heart and padlock emojis.

She had to know what fans would think, but again ... we're told there's no engagement.
