DeAnna Pappas promises an exciting appearance in The Bachelor episode, when she found out that Mesnick would be the next Bachelor.

In an interview with People magazine, the 27-year-old says she can't reveal why she returned, after rejecting Mesnick's proposal on last season, but she insists it is worth the wait.

Unfortunately everyone will just have to watch and see what I am doing there. It will be worth the wait. The women were not that happy to see me, I can tell you that, she said.

I was very happy for Jason. We talked a lot before we went on. I told him it would be one of the best experiences of his life and that he would form many wonderful friendships and fall in love. I warned him that it is wonderful and hard at the same time, Pappas said.

Pappas also revealed about her split three months ago with ex-boyfriend Jesse Csinsak after they both realized they wanted different things in life, I loved him sincerely, but it would not have worked in the long run. There is no chance of the two getting back together, she said.

The Bachelor airs Monday nights at 8 p.m. on ABC.
