ST LOUIS (LALATE) – The Bachelorette 2012 winner isn’t going to be revealed by Arie Luyendyk Jr. anytime before Sunday. Arie is leaving who Bachelorette Emily Maynard picks a mystery down to the finale. Luyendyk won’t even tell fellow racer Mario Andretti who wins the Bachelorette 2012 this Sunday night, the reality star told admitted to news this week.

While earlier in the season Arie suggested to news that he is the Bachelorette 2012 winner, Arie is not giving any tips to friend Mario Andretti. And Andretti apparently hasn’t seen the online spoilers, either. Those spoilers have already revealed that Sunday’s Bachelorette 2012 winner will be Jef Holm of People Water.

Producers are trying to make the finale Sunday night a surprise, even though it isn’t for many viewers beyond Andretti. Emily tells Chris Harrison this week “The fact that I still don’t know who the guy here is the one for me, makes me wonder if any guy here is for me.”  She adds “I don’t know where my heart is any more.”

Harrison tries to evoke suggestions that Emily doesn’t really know who she wants to pick Sunday. But, it’s a familiar theme for finales of the franchise. Yet, come Sunday night, Emily Maynard will know exactly which man she is going to pick (Jef), despite Harrison’s suggestions.

“It sounds like you know what you need to do,” Harrison tells Emily this week. “You feel like at this point you’re betraying both of them.”

But then, there have been those alleged false spoilers this month. One false report claims that Emily picks Arie, that Arie declines and that Emily switches and picks Jef. The culprit behind this purportedly false spoiler is In Touch. “He said, ‘I don’t think we know each other nearly enough to even be entertaining this; I don’t think we should get engaged,’ an insider told In Touch. “She was crying and begging him to reconsider,” the source said, adding that Maynard even blurted out “You’re the one I want to pick!” Reality Steve and others have claimed that none of that happens in the finale.

For now, Andretti doesn’t know who is the winner either. Arie tells the IndyStar “(Mario) always tells me he better be invited to the wedding (and) he needs to know the outcome so he can plan for a good wedding gift.” Arie added “Just wait and watch.” Despite Andretti’s curiosity, online spoilers for weeks have claimed that Emily picks Jef, that Jef and Emily get engaged, that the two are still together, and that they are planning a fall wedding.
