Denise Richards showed up to a Los Angeles court today with her father Irv.  It is not certain why Denise was there (she certainly wasn't giving up any details) but there has been increased tension with ex-husband and father of her two daughters Charlie Sheen, due to the release of some pretty explosive voice mails that he left for Denise. Sheen has since apologized for the messages but noted in statement, "And for the record, my children did not show up today for a custodial visit without explanation...So three and one-half years later, the reasons that caused the anger and frustration displayed on that voice mail continue to be manifested on a daily basis."
