Krejcir appeared in connection with an alleged escape plan and his possible extradition to the Czech Republic.
He laughed and chatted with his former mistress and co-accused, Playboy playmate Marissa Christopher.
Krejcir's cases were postponed to April but Christopher's lawyer Zair Omar theatrically argued for his client, who has a two-year-old daughter with Krejcir, to be allowed to talk to him to discuss the child.
The Czech walked down the stairs and joked that he's still kicking.
