Seal – Off to Germany still wearing his wedding ring!!

Seal‘s finally left Heidi Klum — he flew out of the country last night … and did it with a you-know-what eatin’ grin on his face.

The singer wasn’t looking like a guy whose wife is divorcing him as he boarded a flight to her native country of Germany — smiling for the cameras waiting outside LAX.

By the way, Seal was still wearing his wedding ring.

Right before heading to the airport … Seal fueled ridiculous speculation his split from Heidi is a PR stunt to pump up record sales by performing on Jimmy Kimmel Live.

He sang … “I’ll Be Around.”

Seal’s Temper Leading Cause Of The Breakup?

Heidi Klum is divorcing Seal largely because she has had it with his volcanic temper …

Sources directly connected with the couple tell us … Heidi’s decision to divorce Seal has nothing to do with a third person. There is NO issue of infidelity.

But Seal’s inability to control his anger has become too much for Heidi to take, in no small part because it’s affecting their children.

TMZ broke the story that Heidi will divorce Seal, and we’ve learned this was not a snap decision. As one source said, “It was a long time in coming.”

We’re also told … their careers also played a part in Heidi’s decision. She has become a mega-entrepreneur and extremely rich, and that professional evolution has created a distance between them.

For his part, Seal has a new album coming out and he’s about to launch an international tour.

We’re told Heidi and Seal are still living under the same roof, but that will change very soon.

Heidi’s rep told PEOPLE that the couple was separating, but as TMZ first reported, Heidi wants a divorce. The couple says, “We have had the deepest respect for one another throughout our relationship and continue to love each other very much, but we have grown apart.”

Heidi Klum To File for Divorce From Seal

Heidi Klum will file for divorce from Seal … TMZ has learned.

Sources with direct knowledge tell TMZ … Heidi will file divorce papers in L.A. County Superior Court as early as next week. We’re told Heidi will cite “irreconcilable differences” as the cause for the divorce.

The couple married May 10, 2005. They have 3 biological kids. Seal adopted Heidi’s eldest girl from a prior relationship.

The couple is famous for renewing their vows every year on their anniversary … in a lavish ceremony.

As for splitting up the goodies, there’s a lot on the line. According to Forbes, in the last year alone, Klum raked in $20 million. It’s unclear how much Seal made.

Heidi attended last Sunday’s Golden Globes without Seal. The last photo she tweeted with him was back on December 26.
