Actress Estella Warren has been in a rehab treatment center since May following her arrest for DUI and her subsequent crazy antics in jail and RadarOnline.com has exclusively learned that she is getting a weekend pass to attend a charity event out of the country.

“Estella is getting a short pass to leave her treatment center and she is being escorted to the event by a sober companion from the offices of the treatment facility,” her lawyer Darren Kavinoky exclusively told RadarOnline.com.

Estella is a celebrity sponsor for the Rally for Kids with Cancer being held this weekend in Toronto, Canada.
