Seeing that she too was scheduled to perform at BBC Radio 1's Hackney Weekend over the weekend, it would have been almost rude for Rihanna not to make an appearance during the show of her boss, mentor and friend Jay-Z.

Above is a video of Rihanna popping in to sing her part on Jay-Z's “Run this Town.”

The crowds sure love these two, especially when they're together.

Rihanna also performed on her own, closing Hackney Weekend with an hourlong performance that included some of her biggest hits, including “Disturbia” and the more recent “Where Have You Been,” as we also informed you earlier today.
