‘He is really into her’, the insider alleged.

The source claims Timberlake, 28, and the Umbrella star, 21, have been meeting together in New York.

It is not the first time the pair have enjoyed time together after JT helped out the Barbadian beauty in a raunchy video shoot during her third album Good Girl, Gone Bad.

Timberlake is also lending his skills to the star’s next record, which could be a good reason for the sightings.

Only this week he spoke about their time in the studio together telling: ‘The stuff we’ve come up with in the studio, it’s the next step for her. It’s a little more grown-up. It’s got some edge to it.’

But the mole also alleges playful Rihanna recently gave Timberlake a lap dance at the 10ak night spot in NYC.

The claims come after Timberlake was accused by Lindsay Lohan of being a ‘cheater’ on Twitter after he was spotted dancing on a bar table with a mystery woman earlier this year.

He also put in a lip-lock photo opportunity with Biel, 27, at a basket ball game after he was accused of ‘acting like a single guy’ at a party thrown by ex Kate Hudson.

A spokeswoman for Rihanna would not comment on her personal life and Justin Timberlake’s representatives did not return our emails.

Yes, I just quoted a line from Baby Got Back and I’m damn proud of it.  In other news Jessica Biel is now blonde.  The new ‘do is to accommodate her role in the upcoming film ‘Easy Virtue.’  I don’t get it…is she supposed to look like a prostitute?  I mean, if she wasn’t don’t you think they should have given her a nice dye job?     Jessica said that she was considering keeping her hair blonde because of how it’s affected her attitude…she’s more flirty and fun.  Last time I checked blonde hair doesn’t give you the right to be a slut.  I guess she missed the memo.

Miss Biel revealed, “I loved having blonde hair.  There is something really sexy and wild about being a blonde. I loved it. It was super fun, and I will do it again one day.”

Jessica Biel really needs to stop talking.  She already said that she doesn’t get roles because she’s too pretty (yea, that’s it) but now she’s saying she won’t leave the house unless she is completely done up.  She says she spends a long time getting ready mainly because she knows that the paparazzi follow her and she doesn’t want to see fugly pics of herself in mags.  Yea, that’s what happens when you call the paparazzi, Jess.  She’s about as exciting as a pet rock if you ask me.  She and her lips need to just stop talking. K, thanks.

“Yeah it really is a problem. I have to be blunt.”

She continued, “I’m in there with everybody else, fighting for the good parts. Yes, The Illusionist has made a difference—but a huge, massive difference, so I can pick and choose what I want? No.”

The 27-year-old actress says she wishes she could score gigs like Scarlett Johansson and Natalie Portman. “I just want an opportunity. If you don’t like the audition, don’t hire me!” she says. “But if you don’t want to even see me—that’s hurtful. And why? You know nothing about me!”
