Justin on Jessica

Things between Justin Timberlake and Jessica Biel are going from hot and heavy to steady and serious.

As the pair continue to get steamy in Europe, the duo now become a trio.

Yup, Mister JT’s new girlfriend was spotted yesterday shopping with his mom, who is on tour with him, in Oslo.

Seems like Biel’s got the very important mom seal of approval.

Justin’s mother reportedly hated Cameron Diaz.

We can’t say we blame her!
