"Seal's dropped everything to be by Heidi's side and try to lift her spirits," an insider exclusively told RadarOnline.com.
"The connection between these two never went away, and was actually a big reason why Vito couldn't commit."
As Radar reported, 31-year-old Schnabel, who was recently arrested on drug charges, and Klum, 44, have decided to call it quits on their three-year relationship amid rumors he was straying on the Project Runway host.
"Vito always felt second best to Seal, who would be on the phone to Heidi night and day and dictating her schedule due to their shared commitment to the kids," Helene, 13, Henry, Johan, 10, and 7-year-old Lou.
"Seal has no shortage of girls to casually date, but he's still hopelessly in love with Heidi," revealed the insider.
"Everyone's predicting it's just a matter of time before they get back together."
