Lohan dating Sonny Bono's Son In Rehab

Lindsay Lohan has fallen for late hippie icon Sonny Bono's son Chesare, according to our sources.

After reportedly helping to break up rocker Tony Allen's marriage to British heiress Stephanie Allen, the Mean Girls star has now found love again in rehab.

And this time, the object of her affection is the late Congressman's teen son.

Chesare, 19, checked into the same Utah Rehabatorium as Lohan to battle a painkiller addiction last summer and friends claim the two have become an item.

Our source said, "Chez is telling pals that he and Lindsay have fallen for each other big time"

"They say our love won't pay the rent, because the money's already spent...."
