The Baby hitmaker was set to team up with WWE stars John Cena and Big Show for a six-man match at the big SummerSlam event in Los Angeles in August (14), according to former WWE writer Kevin Eck, who was part of the booking team working on Bieber's deal.

Eck admits he had concerns about the pop singer's troubled reputation, fearing Bieber's involvement could reflect badly on WWE and on star wrestler Cena.

He writes in a post on his sports blog, "Everyone knows that pop star Justin Bieber is a member of (boxer) Floyd Mayweather's entourage. What isn't known is that Bieber... was interested in stepping into a WWE ring last summer to make his wrestling debut. The idea was that Bieber would team with John Cena and Big Show to face the Wyatt Family in a six-man tag match that would have headlined SummerSlam in Los Angeles.

"The proposed match was discussed among the booking team (which I was on) about five months before SummerSlam, but a deal with Bieber never came to fruition... My concern at the time was that Cena teaming up with Bieber - who was making headlines for all the wrong reasons and most definitely would have been booed unmercifully by the WWE audience - would not have done Cena, the face of the company, any favours."

However, Eck is adamant Bieber could still turn up in a wrestling ring in the future, adding, "It certainly wouldn't surprise me to see Bieber do something with WWE at some point."
