Lindsay Lohan has lashed out at funnyman George Lopez after he made a quip about bizarre pictures of the actress with white powder on her feet.
The Mean Girls star was snapped on Saturday (27Mar10) leaving a friend's home in Los Angeles with mysterious clouds of dust billowing from her designer shoes.
The photos fuelled fears Lohan is spiralling out of control, and her father Michael is planning to hold a press conference on Tuesday (30Mar10) to discuss "Lindsay's state of well-being and the direction he will take to help her through this life-threatening and difficult time".
On Monday (29Mar10), comedian Lopez jokingly claimed Lohan uses baby powder to loosen her tight high heels - but the remark sparked a furious reaction from the star.
Taking to her page on Twitter.com, she aimed a barbed comment at the funnyman, telling him: "Thanks for the childish comment regarding baby powder in my shoes to loosen up the leather. Don't you have kids? U wouldn't wanna hear that about them, or would you? Act like a grown man, have some respect and dignity for yourself."
