Teresa & Joe Giudice -- We Got Nothin' to Say ... Except to Andy Cohen!

Teresa and Joe Giudice blew past reporters Thursday after they were sentenced to prison ... but it wasn't because they were too upset to speak ... it's because they were ordered to shut their traps until Andy Cohen could ask them, Wasssup?

Our Giudice sources tell us ... the felonious couple will break their silence Monday on a special "Watch What Happens Live: One-on-One with Teresa and Joe."

It's pretty funny ... when Teresa was begging the judge for mercy she was quick to say she didn't give a crap about TV anymore. What she FAILED to disclose is that she had a secret deal with Andy!

As for what's on Andy's docket ... we're told he'll discuss the Giudice's fears, family and fraudulent ways.

Gotta say ... brilliant move on Bravo's part. And ... it's not like the judge can sentence her for lying ... something Teresa's clearly got down pat.
