Actor Ashton Kutcher is reportedly giving financial help to troubled actress Lindsay Lohan.

Kutcher, who reportedly had brief fling with Lohan in the past, feels obligated to let Lohan treat him like her own personal cash machine.

"Ashton has always had a soft spot in his heart for her, and Lindsay totally exploits it," showbizspy.com quoted a source as saying.

"She has been asking to borrow hundreds of dollars at a time with the promise to pay him back 'in a couple of weeks.' Ashton knows he's never going to see the money again, but he's very loyal," the source added.
