'Cake Boss' Star Sports Buttercream Jail Jumper

Dressed in his yellow jail uniform -- "Cake Boss" co-star Remy Gonzalez strolled into a NJ courtroom this morning ... where the man accused of sexually assaulting a minor learned that he will face a grand jury.

As we first reported, Gonzalez -- who is married to "Cake Boss" Buddy Valastro's sister -- was charged with aggravated sexual assault, sexual assault, criminal sexual contact, and endangering the welfare of a child after his August 18 arrest.

During a brief hearing in New Jersey today, the judge decided to refer all charges against Gonzalez to a grand jury -- which will ultimately decide whether the case will go to trial.

Gonzalez is being held on $300,000 bail.
