When the Stronger hitmaker headlined the Pyramid Stage at the fabled music event in Somerset, England, the BBC aired a live stream of the performance which included hits FourFiveSeconds, All Day and Touch The Sky.

Following the broadcast, 44 viewers complained to British regulatory body The Office of Communications (Ofcom) about offensive language used in the performance, but BBC chiefs insist that as the show aired after the set U.K. watershed of 9pm there should be no problem.

An Ofcom spokesperson tells WENN, "(We had) 44 complaints about offensive language in Kanye West's performance. We will assess these complaints before deciding whether to investigate or not."

A representative for the BBC responded, "This was post watershed and clear warning notices were given that the performance may contain strong language."

The scenario mirrors the reaction to West's controversial performance at the BRIT Awards in London in February (15), when his excessive swearing during a rendition of All Day provoked 151 viewer complaints.
