The Dumb and Dumber funnyman was seen kissing McCarthy before the pair jumped into a limousine.
McCarthy, a former Playboy model, was whisked away in a helicopter from California's Santa Monica airport for a long weekend in Long Beach.
According to The Sun, they started their weekend with a romantic dinner on board The Queen Mary.
The couple have reportedly been dating for months in secret, but this was the first time that they have been photographed together.
