It has recently been reported that Beyonce might have cheated on rapper husband Jay Z with her bodyguard Julius De Boer, consequently putting the hip-hop power couple's marriage in jeopardy.

De Boer instantly became famous when he pretty much saved the hitmaker from a vicious attack by his sister-in-law Solange Knowles, as captured in the surveillance video in a hotel elevator.

Although the bodyguard may seem loyal and professional in the recent footage, Jay, who himself became the subject of infidelity since the elevator incident, has reportedly gotten quite suspicious of his wife's relationship with De Boer. He has been wanting to get rid of him, which the R&B diva strongly not in favour of.

`Jay definitely thinks that there was and may still be something romantic going on between Bey and Julius,` a source revealed. `He wanted to fire Julius last February, but Beyonce said, 'Julius isn't going anywhere.'`

Also, many were skeptical of Beyonce and De Boer, as they became unusually close to each other. They were even spotted leaving a hotel together back in 2009, with the bodyguard's lips smudged with the 'Partition' singer's signature red lipstick. `They've spent a lot of time together behind closed doors,` the insider added. `He's even stayed in her hotel room.`
