Jessica Simpson's Dad -- Out and About with Fab New Look

Just days after news broke of the demise of his marriage, Jessica and Ashlee Simpson's newly single father Joe Simpson was spotted out in L.A. on Thursday sporting a much more, er, youthful look.

Doing his best Ellen DeGeneres impersonation, the 54-year-old rocked blonder highlighted locks, a fitted yellow sweater, black skinny jeans and matchy matchy spiffy kicks.

As TMZ reported, Joe's wife Tina Simpson filed for divorce last month -- after being legally hitched for 34 years -- claiming their marriage has become "insupportable because of discord or conflict of personalities."
