New Delhi, Jan 9 (ANI): Jennifer Aniston feels that it must have been her deceased first love, who sent her current beau Justin Theroux. The 45-year-old 'Cake' star, who's happily engaged to 'Leftovers' actor, made a huge revelation saying that she was with someone for 5 years, who could have been "the one" but he died of a brain tumor, a leading news network reported. In an interview with the New York Times, the actress explained that she was only 25 at the time and "stupid," and that he was an "unappreciated boyfriend." "He must have sent me Justin to make up for it all," said Aniston. Talking about Theroux, Aniston said that it took her some time to get used to the engagement ring, since she wasn't a "diamond girl" and liked more of Indian jewelry.
