Simpson, who is looking into studying theology at a university level, combined a plaid shirt and bright-yellow sweatpants (with what looked like a bluebird emblazoned on them) and big furry boots.

Someone may have been late for her flight!

Or perhaps recent rumors that Jess has practically moved into boyfriend Tony Romo's Dallas home are true.  She's completely given up looking hot now that she's managed to find a place for her Sonicare toothbrush in his medicine cabinet.

The pair has been dating since 2007.

"She helped him decorate the house. She really took the reins," a source told Us.

The older Simpson sister can relax now and trade in the cleavage-flashing halter tops for comfy sweats and Tony's old shirts now that she's with the "right one."

The only problem? Romo, 28, has a roommate.

Look for that guy to be kicked to the Dallas curb soon.
