Sen. John McCain has  lost Paris Hilton’s vote by using her image to help brand Sen. Barack Obama as just another worthless, mindless  "celebrity" in his TV ad.

But ironically, while he’s comparing Obama to Paris and Britney Spears, his own daughter Meghan McCain has been busy trying to become one of them.

She’s been seen sucking up to "The Hills" star Heidi Montag at a trendy Santa Monica restaurant.

And last month, she got  her hair done at a swank WeHo hair salon — John Frieda on Melrose Place — frequented by celebs Kate Hudson, Renee Zellweger, Meg Ryan, Jane Fonda and Lisa Rinna.

And guess who cut Meghan’s hair into a hip Hollywood shape? Matthew Shields, Jane Fonda’s hairstylist. But don’t ask him about it. She made everyone sign a confidentiality agreement! Just like a real star!

Oh, it’s’ just too delish.

Hilton’s rep has spoken out against the new TV ad from the presumptive Republican presidential candidate, in which images of Spears, Hilton and Democratic challenger Obama appear on the screen as a voiceover intones, "He’s the biggest celebrity in the world. But is he ready to lead?"

"Miss Hilton was neither asked, nor did she give permission, for the use of her likeness in the ad, and has no further comment," her rep said in a statement to People.

And d’oh! Seems McCain’s peeps must not have done their homework. Hilton’s parents actually donated $4,600 to Johhny’s campaign earlier this year.  Now you slam their daughter? Way to win voters and influence donations, J-Boy.

Oddly, McCain’s ad did not contain images of two of his own biggest celebrity supporters, Spencer Pratt and Heidi Montag. At the time of Heidi’s hearty endorsement, McCain returned the compliment by claiming he never missed an episode of her reality TV show.

"The Hills" star Heidi had a lovely lunch with McCain’s daughter, Meghan, a few weeks ago at the Ivy at the Shore, a big celebrity hangout in Santa Monica.

That same week, Heidi had her hair cut and colored by celebrity stylist Matthew Shields (who also used to do Ellen DeGeneres‘ locks) and colorist Negin Zand (she colors Kate Hudson, Angelina Jolie, Sarah Jessica Parker, Scarlett Johansson, Cate Blanchett) to prepare for her upcoming press and TV interviews.

And she’ll probably be seeing Matthew and Negin again at snipper-to-the-stars Sally Hershberger‘s new buzzed-about celeb hair salon, which opens later this month on La Cienega with a big star-studded bash.

So who you calling "celebrity," John? Looks to us like you’ve got a celebrity wanna-be in your family.

Hey, we’re just saying …
