EXCLUSIVE: Comedian George Lopez Angers Family With Secret Burial

This is not a laughing matter. The family of George Lopez is furious at the comedian after he secretly buried his beloved grandmother without their knowledge, RadarOnline.com has learned exclusively.

"George buried our grandma and didn't tell any of us about it," his sister Linda Sierra told RadarOnline.com. "He didn't let any of us know -- George's sisters, nephews and nieces are all heartbroken." A niece echoed her statements.

Benita Gutierrez was rushed to Holy Cross Hospital on August 12, where she eventually died, according to Sierra. Lopez apparently had her laid to rest at Glendale’s Forrest Lawn Memorial Park and left family members out of the service and burial.

A rep for Lopez did not immediately return a request for comment.
