Hill rats, keep your eyes open: NBC 4 is reporting that Jessica Simpson, post-Nick Lachey, is over on the Hill today. The NBC story even has a supplemental “Jessica though the years” photo slideshow album. Simpson is in town representing Operation Smile, for which she serves as its International Youth Ambassador. The organization does good deeds in third-world countries by treating children and young adults with facial deformities like cleft lips and cleft palates. Three cheers to Simpson flexing some altruistic muscle. We’d like to get our hands on some of the talking points she’ll use when speaking to the representatives: any thoughts on what those would be like?

While deciding to visit the Hill, MTV News informs us that Simpson has turned down an invitation to meet President Bush at the National Republican Congressional Committee gala fundraiser this evening, as she didn’t want to politicize the non-partisan Operation Smile. A source told Reuters that Simpson, “would love to meet the president and talk about Operation Smile…but she can’t do it at a fund-raiser for the Republican Party.” If only some of our elected officials would be as careful with their causes. The article also notes that Simpson keeps her own political views private.

We couldn’t bring up J Simp without talking about her latest ad campaign: it’d make us smile if she stopped with those “these bites are made for popping” spots for Pizza Hut. Imagine some of those pizza bites with a side of her Dessert Beauty body products line. Gross.
