Social media platforms were abuzz on Tuesday morning, as rumours spread that hip-hop artist Big Sean cheated on his girlfriend, singer Jhené Aiko. 

The speculation started after fans noticed that Aiko  un-followed the hip-hop rapper on Instagram last night, and then re-followed him earlier this morning. 

Aiko's actions may have sparked fan theories about the rapper's alleged cheating, due to Aiko being on tour in Pacific Asia, and apparent sightings of Big Sean following dancer and singer Nicole Scherzinger on Instagram.  

Aiko and the rapper have been together for over four months, following Aiko's divorce from former husband, producer Dot Da Genius. 

Twitter CSI responded to the alleged cheating rumours by pulling receipts on previous claims that Aiko cheated on her ex with Big Sean before she filed for divorce at the end of 2016. 

Aiko was quick to dispel the cheating rumours with two tweets from her personal Twitter page, which Big Sean later retweeted, quoting Aiko's tweets with two applause emojis.
