Jessica's Second Helpin'?

Oh no she didn't. If there is such a thing as bad karma, then it's been having a ragin' party in honor of some A-listers lately. First, Paris Hilton, freaks out over Lindsay Lohan gettin' cozy with her ex, Stavros Niarchos (this comes after Miss P, stole him from Mary-Kate Olsen), now comes word that Jessica Simpson might be taking her feud with Lindsay to the next level -- by dating her ex, Jared Leto! People reports that the "maybe" couple met at one of Jared's concerts in LA and have been secretly dating ever since. "[Jared] partied solo at New York City's club Plumm, then headed to Double Seven, where he met up with Simpson," snitches the mag. "They were hanging all over each other," says a witness. Needless to say, La-La is reportedly not amused. "She's telling friends she's furious," says a source. "She feels betrayed by Jared." But publicly, Lindsay's new cool-as-cucumber stance says otherwise (at least that's what her mouthpiece is spinnin'). "Lindsay could care less," she insists. Oh really? Then let's see what happens if we put all three of these relationship recyclers in a room together. We bet they'd get along great -- until the cameras and the tape recorders were turned off. Meooow.
