'He's pretty adamant about it:' Did no-sex vow cost Tebow relationship with Miss Universe?

Did sex – or lack of it – end Tim Tebow’s relationship with Miss Universe? Or was it something more mundane?

The internet is abuzz after the New York Daily News reported that 23-year-old Olivia Culpo dumped the former NFL quarterback because of his famous no-sex-before-marriage vow.

Tebow, a devout Christian, is known for bending to one knee in prayer during games.

"She had to break up with him because she just couldn't handle it,” the Daily News quoted a source as saying. "He still hits her up, but she just can't deal with the sex thing. He's pretty adamant about it, I guess."

US Magazine – quoting an anonymous source of its own, of course – reported that the reason for the split was somewhat more mundane.

"He was very into her,” Us reported the source as saying. "But she just got out of a long-term relationship, and was not interested."
