Us Weekly Wednesday said Tebow, 25, and Belle, 26, were breaking up after dating for less than two months.
The devout-Christian quarterback and the "Push" and "Breakaway" star had first been seen together publicly on Oct. 30 at the family-entertainment complex Latitude 30 in Jacksonville, Fla., where their date included bowling, said TMZ.com.
Tebow has been falsely linked in the media to "Glee" star Dianna Agron and singer Taylor Swift, Us said. Belle dated singer Joe Jonas from September 2008, when they met on the set of the Jonas Brothers' music video for "Lovebug," through July 2009.
Describing what he looks for in a woman, Tebow said in the October issue of Vogue that, "Obviously looks play a big part. Being attracted to someone plays a big part, but there's also so much more than that for me. It's about finding someone sweet and kind -- and that has a servant's heart."
