Never mind the fact that Justin has a long-term girlfriend in the dull as dishwater actress Jessica Biel, that doesn't seem to make any difference to the story.

Apparently Justin is 'really into' Rihanna and the pair have meeting meeting up for secret dates in New York behind Jessica's back.

The pair starred in a music video together not long ago and on set sources say the chemistry between the two was 'sizzling'.

Now other sources claim Justin is close to calling it off with Jessica and going public with Rihanna.

Hmmm this seems very unlikely but who knows - it is LaLa land after all!

UPDATE: Justin and Jessica have announced their split! Apparently the couple had been arguing for weeks and Justin decided to end it over the phone.

So this rumour isn't looking so crazy now after all!

UPDATED UPDATE: Snooze they're back together - are they just playing games now to incite some interest into their boring relationship?
