Larsa Pippen might be wearing a rock on a certain finger lately, but hold the wedding bells for now ... 'cause she ain't walking down the aisle just yet with Marcus Jordan.
The on-and-off-again couple has been at the center of speculation for over a week now -- and that was kicked into high gear on Valentine's Day when LP stepped out with Marcus in Miami with a massive diamond ring on her left ring finger.
Indeed ... it was very suspicious, but despite people thinking they might be engaged -- this after patching things up fairly quickly following a little spat -- sources with direct knowledge tell us it just isn't so.
