chad faust adrianne palicki getty 'Lone Star': Chad Faust cast as Adrianne Palicki's ex husbandThe 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.
