Jennifer Hudson "Still in Shock" at Chicago Hotel

Actress who lost her mom, brother and nephew has been holed up in a downtown Chicago hotel and has not been seen in public since Monday

Jennifer Hudson has been holed up in a downtown Chicago hotel with loved ones and friends as she prepares to bury three family members.

"She is still in shock," a source tells E! News. "She hasn't gone out much at all and has a lot of security around her."

E! News has confirmed that Hudson checked into the Trump International Hotel & Tower on Oct. 24, the day her mother, Darnell Donerson, and brother Jason Hudson were shot and killed in Donerson's home and nephew Julian King was reported missing.

Donald Trump himself offered up the hotel suite for Hudson and her family to stay in free of charge.

Hudson had been in Florida when she received the news and immediately boarded a flight north.

Since her arrival last Friday, Hudson has rarely left her hotel suite, sources say. She has had her cousins run errands, including picking up personal items from her downtown condo and bringing in food.

Hudson hasn't been seen in public since identifying her nephew's body at the Cook County Medical Examiner's Office on Monday.

Sources close to the Oscar winner tell E! News that her family and fiancé David Otunga have been her rock throughout the week. In fact, Otunga has been with her around the clock.

"David's been by her side through this whole tragedy," a family source says. "He has totally been there for her."
