Dancing With the Stars: Sean Lowe Talks Tonight's "Attention-Grabbing Outfit" and Wedding Planning With Catherine

Exclusive! The Bachelor star reveals to us that Catherine has yet to see him perform as he won't let her come to rehearsals for the ABC reality hit

Put on your dancing shoes 'cause Dancing With the Stars is back tonight!

One of the front-runners going into the premiere of the ABC reality hit? The Bachelor's Sean Lowe, who announced he was joining the show just after his engagement to Catherine Guidici was revealed. We were lucky enough to talk to Sean and his partner Peta Murgatroyd during one of their rehearsal sessions, where Sean couldn't stop gushing about Catherine! "I couldn't ask for a better fiancée, because she's understanding that I have to put it in a lot of hours here but she's rooting for me," he tells us. "She's in my corner. She's going to be in the front row cheering me on."

But if Catherine is so supportive of Sean's Dancing With the Stars gig, why hasn't she been to a single rehearsal?

Sean actually won't let Catherine come! "I want it to be a big reveal," Sean says of his big debut tonight. "She'll be there in the audience. She keeps asking for me to show her clips on my iPhone and stuff, but I just want her to wait and for her jaw to drop and go, 'Woah, where did Sean learn how to do that?!'"

While Sean is busy at rehearsals, is Catherine planning their upcoming wedding, which will be televised? "She is a planner, so I'm sure she's started on that and hey, by all means, take it away!" One thing Sean is planning on doing at the wedding is his go-to move: The hip thrust. (PSA: He demonstrates it in the video. You're welcome, Internet!)

And yes, Bachelor fans, Sean's partner Peta totally plans on using those rock-hard abs to her advantage, so sexpect a lot of shirtlessness! "It will definitely come off, I'm just not sure when it will come off, but hopefully in the Latin dances it's going to be teared away," Peta says. As for what he will be wearing tonight, Sean teases, "It's an attention-grabber!"

Dancing With the Stars returns tonight at 8 p.m. on ABC.
