Justin Bieber and Rihanna hooked up?   That is definitely an unlikely duo.

According to Life & Style not only did the musicians hook up, but their pairing could be the reason for Selena dumping Justin.  While the magazine is claiming the hook up occurred at the beginning of Selena and Justin’s relationship, Gomez just found out about it and this may be the cause of the latest breakup for the couple.

Since Life & Style is not the most reliable sources – I would definitely not bet on this hook up.  Almost like the time Justin hooked up with Kim Kardashian – it never happened.

The magazine claims a “source” said that the news of the alleged affair has “devastated her.  It really cut like a knife because it happened in February of 2011, when Selena and Justin had been dating for months and were falling in love. It’s caused Selena to question their entire relationship.” 

According to the friend, Bieber and Rihanna were said to have hooked up after an evening of flirting at a basketball game in February 2011.   I am sure there are photos out there and there is definitely a chance they attended the same game and sat next to each other.  But since when does sitting next to each other mean you hooked up?

What do you think Rihanna’s on again/off again boyfriend, Chris Brown would have to say about the Biebs and his woman?  Yikes! Based on Brown’s history – that could get really ugly.

What are your thoughts on this rumor?  Did it or didn’t it happen??
