Agassi destroys trophies after Shields' TV cameo.

Brooke Shields revealed that her ex-husband, Andre Agassi, was "petulant" and smashed all his trophies after she guest-starred on the sitcom "Friends" in 1996. Shields played the character Erika Ford, who was infatuated with Joey Tribianni, portrayed by Matt LeBlanc. Agassi was in the audience during the taping and stormed out, claiming that everyone was making fun of him. Shields believes that Agassi's addiction to crystal meth at the time may have contributed to his irrational behavior. Shields' documentary, "Pretty Baby: Brooke Shields," will be released on Hulu on April 3.
