NEXT ON "IT GIRL"... EPISODE 4 -It's the first episode of Dance Off, and Dexter relents by giving Veronica a classy dress: "You look lovely in that dress. I presume it meets with your approval. It's from the Judi Dench fall collection.""It's beautiful, Dexter. I appreciate it." -Veronica lets it slip that she finds Dexter attractive: He flashed a sinister grin. "So, you think I have a perfect face and body?" So much for my having the upper hand. -Veronica and Dexter are celebrity escorts at a high school prom and made the honorary king and queen... which means they have to share a dance with Dexter in control. "Just let me lead.""Don't get used to it." Will their first dance be a disaster, or lead to something more?
