Rumours are swirling that Uma Thurman has called off her engagement for a second time to on-off flame Arki Busson, who is father to her young daughter.
According to the Daily Mail, the New York-based actress was struggling with her long-distance relationship with London-based Busson, who was once involved with supermodel Elle Macpherson.
An insider said warning bells began to go off at a gala this month which the pair were due to attend together.
"Uma showed up without her engagement ring or her fiance," the source revealed.
"Arki was scheduled to attend and it seemed clear there was only one reason why he didn't show - because he and Uma are no longer an item."
The couple started dating in 2007 and got engaged some time later before splitting in 2009.
They reunited in 2011, with Busson proposing the following year and Thurman later giving birth to their daughter Rosalind.
A spokesperson for Thurman declined to comment.
