Has Justin Timberlake noticed that Jessica Biel is no longer the hot commodity she used to be and gone in search of a more high profile girlfriend?

That appears to be the news coming out of Hollywood as the Bringing Sexy Back singer follows a pattern in his love life!

When Cameron Diaz seemed to be facing a little down time in her career, her loving Justin, bowed out of the relationship just as he had done with his Mousecateer girlfriend, Britney Spears.

And now, with Biel not receiving the hot scripts for movies or the glamour photo shoots for men’s magazines, Timberlake is on his way…..arm in arm with Rihanna!

A friend of Biel’s told Us Weekly magazine, “It’s over,” and from what we hear, Justin did it over the phone! It was about a month ago.”

Another source reports that, “Rihanna and Justin have been talking and texting on the phone nonstop since the VMAs. She asked him on the phone, ‘Are you still with Jessica?’ And he hinted that things were cooling off between them.”

An insider tells Us Weekly, ‘Jess is in “severe denial and won’t accept” the break-u, there’s no way of knowing if it’s a firm breakup, because with them it’s so hot and cold.”

Timberlake may only have to face the denial and tears from Jessica, but with Rihanna’s ex boyfriend, Chris Brown’s temper being well documented this year after he assaulted the Umbrella singer, Timberlake had better sleep with one eye open for the time being!
