Jennifer Aniston, 44, definitely shows off some sexy moves as she takes on the role of a stripper turned housewife in her new movie, "We're the Millers."

But who taught the "Friends" star those sultry dance steps?

"I had an amazing choreographer, who basically taught me what to do, and I just did what she told me," Aniston told ABC News at the movie's premiere Thursday night.

While Aniston may not have any children of her own, she definitely was a mothering presence on the set with co-star Emma Roberts, 22.

Roberts said that during the three months of filming in North Carolina, Aniston took her under her wing as a veteran actress and as a friend.

"We just hung out, and there were a couple of times when she had some girlfriends over," Roberts said. "We got to have girl time."

Aniston agreed that she got close with the cast, whom she called a "lovely group of people."

"[We were] just trying to get through the day without laughing so much that we couldn't finish the movie," Aniston said. "We had fun dinners on the weekend."

Much of the movie was made in an RV, as the plot focused on the Millers trying to smuggle drugs into the country. While Aniston said she's more of a poolside gal, she "would not turn my nose up to a good RV trip. I think that would be a lot of fun."
