Marc Anthony -- My Vegas Deal Kicked J.Lo's Ass

Marc Anthony now has bragging rights over Jennifer Lopez in one department -- he doubled the insane Vegas salary she's about to get ... with a recent show of his own at Planet Hollywood.

It sounds crazy, but Marc topped J.Lo's $350K per show guarantee when he took home $700K for his one-night-only gig on September 13th. In fact, the contract, obtained by TMZ, actually paid him just over $1 MILLION ... but promoter fees and operating expenses were taken out of that sum.

Of course, Jennifer's scheduled to play 72 shows to Marc's one -- and she'll make more than $26 mil over 2 years.

Bottom line ... Marc won the battle, but J.Lo wins the war.
