If this is true, then we LOVE it!

Although we doubt Jessica Biel will be too pleased with the news.

Rihanna - Rehab on MUZU.

Yes, it's true (well, we don't know if it's true, true, but it's true that there are rumours) - Rihanna and Justin Timberlake are ACTUALLY GETTING IT ON!*

Once again celebsville is rife with rumours and this time they excite us. Justin Timberlake is supposedly spending an increased amount of time with Rihanna under her umbrella, and there's not a lot of room left under there for his girlfriend Jessica Biel.

The pair, who have worked on music together in the past, are reported to have spent a lot of time together in meetings just recently and internet gossip site hollyscoop.com reported: 'Justin and Rihanna have been seeing each other for the past few weeks.'

The source claims Timberlake, 28, and the Umbrella star, 21, have been meeting together in New York and that he is "really in to her."

Whilst we feel sad for Jessica, if these rumours are true, imagine what a power couple JT and Ri-Ri would be! AMAZING!

What do you think? Would they make a good couple? We think JT would make a good boyfriend! Comments please...

*Like we say, we don't know if it's ACTUALLY true, but the idea excites us nevertheless.
