There were plenty of surprises at last night's Summer Jam concert in New Jersey, USA. But one of the biggest was the moment that 50 Cent reunited with his G-Unit team after years apart.
And if that wasn't enough, 50 also used the opportunity to bring Fabolous on to the stage for a live debut of their 'Cuffin Season' remix.

Before the reunion began, 50 was introduced to the stage by none other than Nas as he went on to perform his hit single 'I Get Money.'
During his set 50 Cent introduced G-Unit members Lloyd Banks, Tony Yayo and Young Buck to the stage and the four went on to perform several old mixtape tracks.
