Actress Julia Roberts' mum has been hospitalised following the death of her daughter Nancy Motes.

The Erin Brockovich star's half-sister was found dead from an apparent drug overdose earlier this month (Feb14), and on Thursday (13Feb14), a lawyer for the family confirmed Betty Lou Motes had been admitted to the hospital, but did offer any details about her condition.

Roberts has yet to publicly comment on the personal double blow. She pulled out of two scheduled Tv appearances last week (ends14Feb14) to mourn the loss of her sister.
