Amanda Knox's fiancé joked that their trip to Italy might be "different" this time around - as they returned together for the first time since she was acquitted of her British roommate's murder.
Knox, Sollecito and another man, Rudy Hermann Guede, from the Ivory Coast, were accused of her murder.
The 21-year-old had been stabbed 47 times and had her throat slashed.

Knox wrote in an article for Medium.com pubished Wednesday that she was "polishing up the speech I'm about to give to a potentially hostile audience in Italy". It studies some of the issues behind wrongful convictions.
The Seattle native was 20 years old at the time of the murder of Briton Meredeth Kercher, whose half-naked body was found on Nov 2, 2007, in a bedroom of the apartment she and Knox shared in Perugia.
"Amanda Knox is the icon of trials that the media carry out before the trial in court is conducted", one of the festival organizers, Guido Sola, told CNN.
"While on trial for a murder I didn't commit, my prosecutor painted me as a sex-crazed femme fatale, and the media profited for years by sensationalizing an already sensational and utterly unjustified story", she wrote. "Amanda has been definitively acquitted in court, but in the popular imagination she is still guilty, because she has been the victim of a barbaric media trial".More news: Missouri, Maine, Vermont have abortion access victories
Media outlets around the world reported on Knox's trial, and Knox has made comments since her release about how they portrayed her and the case to the public.
After the decision, Knox, who has been active in raising awareness around wrongful convictions, wrote on her blog that the court's ruling meant her slander conviction was unjust. She also appeared in "Amanda Knox", a 2016 Netflix documentary about her case. "They were playing the "did she or didn't she game" that I was already so, so exhausted of".
Sollecito was acquitted along with Knox, but Guede was convicted and remains in jail in Italy.More news: Trump's press secretary Sarah Huckabee Sanders to leave White House
