Lindsay dating update: "Mean Girls" star is rumored to be dating Hollywood hunk and recently singled from supermodel Gisele Bundchen, Leonardo DiCaprio.

The grapevine is buzzing with news that the couple celebrated New Years at the party that Lohan hosted at Miami's Prive nightclub. Maybe the kiss they shared at midnight is the reason that Lohan was hospitalized the next day from an asthma attack. It would appear that DiCaprio caused young Lindsay to "lose her breath."

According to a source close to Lindsay, "Leo visited [the hospital] every night. He would sneak in through a back entrance wearing a cap which covered his face. He really helped her get through the ordeal, and he showered her with gifts and chocolates to keep her spirits up."

A vacation is allegedly in the works for the two-some, which includes a trip to meet Lohan's 'momager,' Dina.
