Kelsey and Camille Grammer In Court

Kelsey Grammer and Camille Grammer just showed up in court to do battle in their custody case, and it's the first time they've seen each other since they separated.

Now get this ... Kelsey walked into court with his newest wife, Kayte -- smiling, hand-in-hand.  But when it came time to call the case, everyone other than Kelsey, Camille and their lawyers were thrown out -- including Kayte.

And Kayte then walked into the hallway, sat down and teared up.
