Lindsay Lohan loves the kids!

Yesterday, the 26-year-old actress let her maternal instincts kick in when cameras caught her leaving her hotel in NYC holding pal Domingo Zapata's son. Both she and the little boy were all smiles and we must say they look so cute together!

Zapata's a rich artist who was the one who lent his Porsche to Lindsay while she 's in New York. Unfortunately, that didn't work out so well ...

Lohan was arrested after alledgedly hitting a pedestrian with her car after she drove into a parking garage early Wednesday morning. A source has since told X17 exclusively that she might be headed to rehab once again. She just can't catch a break, huh?!
