The pair play pals battling over their plans to marry on the same day in the new comedy movie. Hudson was recently forced to deny reports the pair fell out for real on set - but she provoked further rumors of a rift during an appearance on Monday's The Late Show with David Letterman.

When the host brought up the subject of Hathaway's 2008 split from Follieri, who is currently serving a four-and-a-half year prison sentence, Hudson laughed and replied, "Surprises in life are awesome."

Follieri was convicted on charges of money laundering and posing as Pope Benedict XVI's representative in America in October. And when Letterman asked if Hudson had met Hathaway before the movie, she joked, "We met the Pope."

A spokesperson for Hudson recently said of the feud rumors, "She and Anne have always been good girlfriends and remain good girlfriends. This is ridiculous and couldn't be further from the truth."
