Heidi Klum and Seal are unlikely to reconcile.

The couple announced the end of their almost seven-year marriage last month, although neither has filed for divorce yet.

Both Seal and Heidi initially wore their wedding rings after their split, but Seal has since been seen out in public without his band.

Insiders believe that the couple are yielding to their impending annulment.

"They had both been wearing their wedding rings and had mutually thought they might be able to work it out," one source told People magazine. "But it doesn't look like it's going that way. She is moving forward with the divorce."

The pair spent Valentine's Day separately for the first time in years. Seal was working on TV show The Voice in Australia while Heidi spent the holiday with friends in Los Angeles.

The pair still share their family dwelling in Los Angeles with their four children. While Seal's been abroad, Heidi has reportedly been doing well home alone with the kids.

"Heidi was in a good mood," another source revealed to the magazine. "She seemed happy to be back to her regular Saturday routine with her kids."

Heidi and Seal haven't been speaking with each other often in recent weeks.

"They have had very little contact and Heidi wants to keep it this way," the source continued. "She feels less stressed out now and feels it's best to be away from Seal, so she doesn't get confused about her feelings."
