Slammed!

In a series of increasingly deranged Internet postings, Ryan Adams has tried to ignite a rock-star feud with Britney Spears.

On a fan Web site, Adams described his reaction to meeting the pop princess at a Los Angeles nightclub. “What a fucking gross chunky cheerleader she was,” he wrote. “She had stubby body builder legs and she just reaked [sic]. Fucking bad sunglasses in a bad LA party.”

Once they discovered the online outburst, Spears’s fans responded angrily to Adams’s posts and accused him of being a “stupid trailor [sic] trash wannabe star,” a “fucking loser” and a “FUCKING UGLY MAMMA’S BOY.”

Spears declined to comment.

In other postings, Adams called London garage-punk band the Libertines “fake” and attacked the so-called “new rock revolution” championed by British rock weekly New Musical Express.

Even so, Adams’s new album, Rock and Roll Reverse, ditches nü-country for a pronounced garage-rock influence. One track, “This Is It,” is reportedly a love song for his new main squeeze, actress Parker Posey.
