There's tension in the air on the New Moon set, as its two hotties battle over who has the hottest bod!

We'd never have imagined that Taylor Lautner could feel insecure about his buff body, but he's admitted that he's starting to see RPatz as 'competition'.

Rob has been working away on his abs to get that chiselled, shirtless look and we actually cannot wait to see the results!

Taylor commented: "Rob, he's getting some muscle. There's some good competition." Uh-oh, we hope that isn't the green-eyed monster talking.

We can just imagine Rob and Taylor sweating it out at the gym, with Taylor offering him muscle maximising tips, but apparently, Rob has been building up his bod all on his own.  Taylor said: "No, he definitely doesn't need any pointers at all. He's got it covered."

This is a battle we'd definitely like to be involved in and we're more than happy to judge their pecs in the name of research.

But who do you think has the hottest body? Will the vampire or the werewolf win? 

Comments please!
