'Lone Star': Chad Faust cast as Adrianne Palicki's ex-husband

chad-faust-adrianne-palicki-getty.jpgThe tangled web of "Lone Star" just got another addition. FOX confirms to Zap2it that Chad Faust ("The 4400") has been cast as Harrison, ex-husband to Adrianne Palicki's Cat Thatcher. Faust will appear in at least two episodes.

The casting, as first reported by EW, paints Harrison as Cat's bad-boy mistake who wants to prove that he has changed and try to come back into her life -- and the life of their 7-year-old daughter. We can't imagine that will go over very well with her current husband Bob Allen ( James Wolk).

Palicki tells Zap2it of her character's two men, "She married young and had a child young and obviously it didn't work out ... She sees in Bob the things that were lacking in the past relationship."

"Lone Star" premieres Monday, Sept. 20 at 9 p.m. ET on FOX.
