Rhode Island's own Olivia Culpo is single. Again. Culpo, the former Miss Universe and onetime BU student who broke up with Nick Jonas last June, has apparently ended her two-month relationship with Tim Tebow. Why? Well, the Heisman Trophy winner is deeply religious and, according to The New York Daily News, his abstinence-until-marriage vow may have caused the split. "He was sending her love letters and cute notes and professing his love for her," a friend of Culpo's told the paper. "She had to break up with him because she just couldn't handle it. He still hits her up, but she just can't deal with the sex thing. He's pretty adamant about it, I guess." In 2009, Tebow, who's a devout Christian, told an ESPN reporter he was a virgin. "I think you're stunned right now," Tebow, who was a member of the Patriots briefly, said during the interview. "I was ready for that question, but I don't think ya'll were." If Tebow is sad, Culpo knows how he feels. After Jonas ended their two-year relationship, she posted a series of sorrowful messages. "Your heart just breaks, that's all," she wrote in a caption to an Instagram photo of a sunset. "Heartbreak is hard but you find more and more things to be grateful for every day."
