The 21-year-old was left in a critical condition after the incident in May and spent nearly a month in hospital recovering from his injuries.
The Beautiful Girls hitmaker was discharged late last month and while he recovers, he hosted a barbecue for friends and family at his home in Miami.
Sean said: 'Time to get stuff ready for this BBQ today...It's going down at the Kingston mansion if you in Miami.'
He added: '4th of july party is popping at the mansion :-) niceeee.'
His rapper friend Soulja Boy was at the party and the pair appeared to enjoy themselves.
Kingston said: 'Man it's going down at the bbq today swag me out!!!!!'
