Patrick Stump Layers Up For 'TRL'

So Fall Out Boy -- sans Pete Wentz, for reasons unclear (ahem, wifeinlabor, ahem) -- are performing in the middle of Times Square on tonight's TRL Finale, and just in case you weren't aware, it's cold outside.

So backstage, FOB frontman Patrick Stump was packing on the layers ... Thermal underwear, you name it.

"I'm trying to put my jacket on, but it's kind of tough," he laughed.

This is a photo of him after he successfully donned said jacket. I told him to look "hot," though I get the feeling he didn't need much direction.
