Lindsay Lohan is going to write a song with Sam Sparro. The Aussie singer and composer will work with the actress after being recommended by Mark Ronson, reports Monsters and Critics. "Working with Lindsay is an interesting proposition. I've always been a big fan and I think she's cool,” said Sam. Mark is the brother of Lindsay’s girlfriend DJ Samantha Ronson. The two ladies were spotted having lunch Monday (July 28) at NYC’s trendy Bar Pitti during a break of ‘Ugly Betty.’
