Seal is scheduled to appear on Ellen DeGeneres' talk show today to promote his new album, and so far it's all systems go ... sources connected with the production tell TMZ.
We're told Seal is supposed to appear in 2 segments -- an interview segment and another where he sings.
The taping is scheduled for 4 PM PT ... and so far Seal's team has not called to cancel.
If Seal does appear, it's possible if not likely that his people will ask that Ellen not talk about the story TMZ broke .... that Heidi will file for divorce.
The show will air tomorrow.
