Page Six was the first to report that Amber has an affair with the 31-year-old international art dealer, 31.
According to a source, the couple dined at New York City hotspot Sant Ambroeus on May 17.
The source said,
They were holding hands while sitting at the table and looked like a couple. She was laughing and put her head on his shoulder for a second, and they grabbed some food to go before walking out, hand-in-hand. It looked romantic.
The two were first caught together in the back of an SUV in NYC on May 9, shortly before the 32-year-old Justice League star left for the Cannes Film Festival.
The couple's romance comes seven months after Vito confirmed his split with Heidi after three years of dating.
Of the America's Got Talent judge, who has since moved on with a new boyfriend Tom Kaulitz, an insider said at the time, "There has been trouble in paradise for a little while".
Additionally, Amber was previously married to Golden Globe Award-winning actor Johnny Depp. They married on 3 February 2015 and just after a couple of years of their marriage, the couple got a divorce on 13 January 2017.
