LATEST: Publicists for Australian actress Abbie Cornish are refuting US reports that their client is the secret reason behind Reese Witherspoon and Ryan Phillippe's shock split.
Articles running in this week's (ends03NOV06) US tabloids claim Witherspoon decided to end her marriage to the CRASH star, 32, after learning he had romanced Cornish on the set of their new movie STOP LOSS in Texas.
The reports go so far as to suggest that the Legally Blonde star, 30, found out about her husband's alleged romance with Cornish after reading a saucy note on his BlackBerry communication device.
But Cornish, 24, insists the reports are all false.
In a statement, released yesterday (31OCT06), her publicist writes, "It's not true. They are co-stars and that is it."
