Common has jumped on Beyonce's infectious 4 track Party to deliver a freestyle over the Kanye West-produced beat.

During an after-party at the Sundance Film Festival last weekend, Common brought a lucky lady on stage with him while he freestyled over the beat, and even kindly dedicated the song to her."

"We can put it all together/ You know the weather/ Me and Jasmine we can find forever," he rapped.

Com had just finished premiering his new film LUV at the festival before his impromptu performance.

It is also the second freestyle he has dropped this month - he controversially fired shots at Drake on Rick Ross' 'Stay Schemin' beat.
