The last but definitely not least cast member to be announced for the set of Dancing With the Stars is the newly engaged former Bachelor star Sean Lowe.

Lowe will be partnered with Peta Murgatroyd, who said in an interview with Andy Swift of Hollywood Life, that it was a challenge to keep their dance partnership a secret.

But Murgatroyd has tweeted Instagram photos of the two dancing. On March 13 she tweeted, "It's time to boogie out the #Murgalo with @SeanLoweksu !!! #Foxtrot."

Though the two are very close in the picture, and the show works best when there is chemistry between the star and the dancer, Murgatroyd said in the interview that she isn't nervous about what Lowe's new fiancé, Catherine Giuduci, will think.

"I think she knows what the show entails, I mean I have to be up close and personal with her fiancé but it's all acting and each dance is different," she said. "I think she'll be fine."

Murgatroyd also said that she has been getting a lot of tweets regarding whether or not Lowe will be shirtless during some dances. "There are definitely going to a couple of times where I take it off," she said.

As far as Lowe's chances, Murgatroyd said he is a strong, masculine guy and she sees him going in to the finals.

Dancing With the Stars premieres on March 18 on ABC.
