Lohan key witness in parents' divorce trial

Lindsay Lohan will be a key witness in her parents' bitter divorce proceedings.

The 19-year-old missed her own film premiere in London last week to fly back to New York for the trial.

Her mother and co-manager, Dina, is suing for divorce and in response her father, Michael, wants a cut of the millions his daughter has earned.

Lohan has a fraught relationship with her father, who is currently serving four years in prison for assault and drink-driving, and arrived at court in handcuffs.
