LL and Rumer Willis have become quite close lately and stepdaddy Ashton Kutcher is not so happy about their friendship. He's evidently been telling Rumer to steer clear of Lindsay. Ashton is very aware of Lindsay's lifestyle (as are we all) through pal Wilmer Valderrama. Here's more:

“Rumer can’t stop gushing about how cool Lindsay is,” a source told the mag. “Rumer feels honored by Lindsay’s attention.”
