Rihanna's Boob Envy, Brooklyn Decker's Butt Envy: MTV's 'Battleship' Chat

What is more fun than a couple of beautiful women talking about how they wish they had more junk in certain trunks? Especially when the beautiful women in question are Rihanna and Brooklyn Decker, flanked by their equally-attractive "Battleship" co-stars Taylor Kitsch and Alexander Skarsgard?

How this topic even came up is still a wonder, but come up it did when MTV News' Josh Horowitz jokingly brought up the fact that while the four easy-on-the-eyes actors are used to being the most attractive people in any room, that wasn't the case when they were all together on set.

"It's really frustrating," Rihanna joked.

"At the end of the day, that's what matters," Taylor added with a smile.

Rihanna then admitted that she did spend some time admiring a certain part of her co-star's anatomy.

"I envy her boobs," she said, pointing at Brooklyn.

"I envy your boobs as well," Alexander joked, but the ladies weren't paying attention.

"Okay. I envy this ass, are you kidding me?" Brooklyn shot back.

"What ass? Where's the ass?" Rihanna asked.

"Stop it," Brooklyn answered. "We can trade for a day."

"I would love to wear that body for a day," Rihanna concluded.

In watching the two lovely ladies go back and forth about their mutual admiration, the expressions of delight on Alexander and Taylor's faces are pretty priceless. And this is just a brief tease of what to expect when we sit down with the cast for our MTV First: Battleship. Don't forget to tune in tonight at 7:56 p.m. ET for the premiere of the exclusive "Battleship" clip and the Q&A with the cast on MTV.com.
