Two months after calling off their engagement, Uma Thurman and Swiss multimillionaire Arpad “Arki” Busson were seen smooching on a bench in New York on Tuesday.
Although Thurman, 39, and Busson, 46, ended their year-long engagement in November, a source told PEOPLE that the couple still “remained friends.”
So are they just pals who happen to lock lips or could they be rekindling their romance? Thurman’s rep could not be reached.
