London, July 18 : Blame it on the cold weather of New York or Jennifer Aniston's daring attitude - the actress was seen "nipping out" on the set of new movie The Bounty Hunter.

The former `Friends' star, who has never been shy of showing off her assets, is currently filming in NY's West Village with co-star Gerard Butler, reports The Sun.

Meanwhile, rumours are abuzz that romance has blossomed between Aniston and Butler.

Earlier this week, the stunner was pictured arriving at work arm-in-arm with the 300 star.

What's more, crew members have reported Gerard has been making her laugh all the time between takes. (ANI)
