Blake Lively and Leonardo DiCaprio hold hands as they walk through the streets in Monte Carlo, Monaco on Friday (May 27).

The 23-year-old actress and her 36-year-old rumored beau spent time together at a yacht party, and a source told Us Weekly that he introduced Blake as his girlfriend.

Once they returned home to the U.S., Blake, Leo, and a group of friends took a late night visit to Disneyland, where they rode StarTours and were spotted out on Main Street and walked down to Downtown Disney.
