Is Britney Spears SERIOUSLY Dating Paris Hilton's Ex??

In Touch mag claims Britney Spears has been dating the ex-boyfriend of her former gal pal, Paris Hilton! According to the tabloid, Brit and Good Charlotte rocker Benji Madden have "been on a few dates" and really seem to like each other.

So how'd the two (alleged) lovebirds meet?

Reportedly, Spears manager "made some phone calls" to potential suitors (including Chace Crawford and Michael Phelps!) and Benji "ended up being the most interested."

We'd say something snarky, but we think we just vomited a little bit in our mouths. Allegedly.

UPDATE: Britney Spears' publicist, Holly Shakoor, barks back with a full denial. "The claims made by In Touch are completely false," she tells E! News. "There is not an ounce of truth to any of it."
