Will they or won't they?

Amid widespread Internet rumors that JESSICA SIMPSON and TONY ROMO are splitsville, a source tells People that the two will make a date of ASHLEE SIMPSON's wedding on Saturday.

The blonde bombshell and Dallas QB met for a casual Japanese lunch at Katsuya in L.A. on Friday, arriving separately and greeting with a kiss, the mag reports. What's more, Jessica's publicist tells People the rumors of their break-up are "not true."

Jessica, 27, will be maid of honor at her little sister Ashlee's wedding to FALL OUT BOY guitarist PETE WENTZ, the mag reports.
