Jamie Foxx remains hospitalised more than three weeks after suffering a medical emergency, and those closest to him say he needs all the prayers and well-wishes his fans can muster.

While his exact condition remains secret - tightly guarded by his family - TMZ has spoken with sources close to Jamie who echo the same plea, "Pray for Jamie."

It was on April 12 when Foxx's daughter, Corinne, announced her father suffered a "medical complication."

Jamie is one of the most prolific players in Hollywood, and his condition has sent studios scrambling.

He has been the host of the hugely popular "Beat Shazam" music lyric game show on FOX, which was going into production just days after he was hospitalised.

Sources with direct knowledge tell TMZ that Jamie will not be on this season of "Beat Shazam."

TMZ is told filming starts today, Wednesday, with a new host. Also Corinne, who DJs on the show, will not be on as well, as she's been a fixture at the hospital in Atlanta by her dad's side.

As earlier reported, Jamie was in Atlanta for work on the film "Back in Action" when he fell ill. A stunt double and body double have been seen filling in for Jamie for that project.
