A British tabloid has published photos of an apparent reunion between Amanda Knox and her ex-boyfriend, who were acquitted after serving four years in prison in Italy for the murder of student Meredith Kirchner.

Knox, 25, and her Italian ex-boyfriend, Raffaele Sollecito, 29, were initially convicted of the crime and sentenced to long prison terms. An appeals court acquitted them in 2011.

Britain's Daily Mirror said Thursday that the pair had a secret reunion, publishing photos of what it said was Knox and Sollecito walking together in New York.

The photos were allegedly taken Tuesday — the same day Italy's high court harshly faulted the appeals court that acquitted Knox and ordered a new appeals court to consider all the evidence to determine whether Knox helped kill Kirchner.
