Sexy Shia LaBeouf had a one-date wonder with superstar Rihanna, but the pair failed to hit it off as lovers. The actor reveals he became "infatuated" with the singer and was stunned to find out Rihanna was trying to get in touch with him. A stylist friend eventually passed Rihanna's details to LaBeouf while he was filming "Indiana Jones and the Kingdom of The Crystal Skull" in Hawaii. He recalls, "(I was) filming a sword fight when I got the message. I said to myself, 'Can this be my life?'" The actor tells Playboy magazine he texted the R&B pin-up and they set up a dinner date: "It never got beyond one date. The spark wasn't there. We weren't passionate about each other in that way, so we remain friends." LaBeouf is also admitting the passion definitely was there on the "Transformers" movie sets, between him and co-star Megan Fox, who plays his girlfriend in the movies. The star still hopes he and Fox can become lovers in the future. He admits they both had to be professional about their relationship while they were working together: "It hasn't been a romantic thing because you're trying to respect the work environment. You don't push anything. And, with sex and romance, things become convoluted so fast. ... You're playing with the devil. "We could be shooting, and the relationship is suddenly on the rocks and then what? So we just never did anything about it. We were very smart. We're attracted to each other, and I think you can see that in our scenes together. It's very real and tangible, and you can tell something exists. "I'm going to know the girl forever. She's a beautiful, intelligent girl, and when you make a movie with someone like that ... you feel things. I know a relationship between us isn't an option for us right now for a variety of reasons ... (but) I get to kiss her in the fantasy world."
