We didn't figure Jessica Simpson for the type to shop for an engagement ring among the mall-dwelling hoi polloi, and it looks like recent reports that she was checking out bright and shiny baubles at a Dallas-area Neiman Marcus with quarterback beau Tony Romo are faker than the locks from her hair extension line. "We are not engaged!" the countrified starlet told "Entertainment Tonight" just before she performed the national anthem -- reportedly with a few lyrical flubs -- to her new fan base at a NASCAR race in North Carolina on Saturday. "Tony and I have not gone to Neiman Marcus -- somebody said we bought a ring there. I couldn't drag Tony into Neiman Marcus if I tried." Despite her diamond-free digit, "Life feels really good right now," swoons Simpson. "I don't really know how much better it could possibly get. ... I'm beyond the moon and stars." And even though Jessica is tempting fate with her repeated declarations of schmoopiness, she doesn't intend to dial it back. "Even if things don't work out between Tony and me -- though, knock on wood, I believe they will -- I don't regret anything I've ever said," she maintains to Australia's Sunday Herald Sun. "That's just how I love. I'm all in and I live one moment at a time. If I'm happy, I'll talk about being happy. Maybe I do talk too much, but I still feel as if I'm holding back." Simpson's idea of holding back includes proclaiming Romo her perfect guy ("It's a beautiful relationship. He's everything I could dream of and I really love him. I'm proud to be his girlfriend.") and revealing her hopes for a Brady Bunch-sized clan ("I'd love six kids running around, but I guess I'll have to start pretty soon.").

You'd think Jennifer Lopez would have had her fill of vowing to stick with someone until death do they part. After all, she's done it three times in the last decade or so. But in the wee hours of Sunday morning, she did it again by renewing her vows to Marc Anthony, whom she wed a scant four years ago. People reports the "spur-of-the-moment" "I do" redo took place around 3:15 a.m. in the superdeluxe Forum Tower Penthouse at Caesars Palace in Las Vegas, with the twin-juggling, image-controlling J.Lo dressed in black and looking "beautiful" as a dozen witnesses looked on. "Her parents didn't even see it because they were with the babies," says a spy. Adds an insider to Us, "It was very intimate and sweet. They both talked about how much they love each other. The word 'forever' was used a lot!" After Jennifer and Marc reconfirmed their still relatively fresh commitment to one another (they were joined in the renewal process by New York Mets player Carlos Beltran and his wife, Jessica), a butler popped a bottle of Dom Perignon. Prior to the vow-swap, the parents of Max and Emme took in the many delights Sin City has to offer, including enjoying a private dinner with the Beltrans before hitting the craps table, taking in a Pussycat Dolls show and hanging out at hot spot Pure.

Unlike Jennifer and Marc, some famous flames don't feel the need to declare the depth of their lovey-dovey feelings publicly (and repeatedly). Johnny Depp and Vanessa Paradis have been happily unmarried for a decade, and they're not looking to mess with their under-the-radar domestic success. "Each summer people say we're supposed to be getting married, but we don't talk about it that much," the French actress-singer tells Elle UK (via People) of long-simmering nuptial rumblings. "He's got me, and he knows he's got me." According to Paradis, "I love the romance of 'let's get married,' but then, when you have it so perfect ... I mean, I'm more married than anybody can be -- we have two kids [Jack, 6, and Lily Rose, 9]. Maybe one day, but it's something I can really do without." She also brushes off the suggestion that she "tamed" the onetime hotel room-trashing squeeze of Kate Moss and Winona Ryder. "Tamed. What's that? Like a lion? Noooo, no, we did it to each other," says Paradis. "Maybe I'm a good girlfriend because I'm his girlfriend. I'm not sure I'd be a good girlfriend to anyone else; the same for him. It's difficult to explain, but it's something that's natural, obvious and beautiful." So beautiful that she doesn't even mind the privacy-loving Depp's ability to attract throngs of the opposite sex. "I understand. I want to mob him all the time, I do," she laughs. "He's a very charming person."

Travis Barker must be feeling more like his old self as he recovers from the severe burns he suffered in a plane crash last month, because he once again seems to be on the outs with lightbulb love Shanna Moakler. In a posting on his MySpace blog, the former Blink-182 drummer thanks fans for their support, pays tribute to his two friends who were killed in the Sept. 19 accident -- and takes a dig at the mother of his two children. "Despite any rumors you might have heard via my EX-wife Shanna Moakler, who I have not seen since the week I checked in, I've been treated amazingly well, both here in L.A. and in Georgia," points out Barker, who told the current issue of Us Weekly that "Shanna has been here as much as she could be." Moakler, who flew to Barker's side after the crash and accompanied him by bus from a burn center in Augusta, Ga., to one in Los Angeles, appears to have fired back at her ex with a message on her own MySpace page, not-so-cryptically writing, "With great tragedies comes [sic] great truths, these truths either bring people together, or tears [sic] them apart..." The rocker, who is facing his seventh surgery this week and has started eating meat again after his doctors told him his protein-light vegetarian diet could affect the healing process, also calls fellow survivor DJ AM an "inspiration," adding, "We are both so lucky and grateful that we are alive today."

Armchair sleuths, fire up the Mystery Machine as you attempt to figure out the identity of the self-adoration-needing star to whom John Mayer alluded during a lecture last week at his alma mater, the Berklee College of Music. In the midst of giving students such sage advice as, "Never apologize ever -- in bed or on stage," the crooner offered them an anecdote to demonstrate how important it is to define their expectations for success. "I sat across from someone one time ... You can't assume who they are -- famous person, friend of a friend," the onetime wooer of Jennifer Aniston, Cameron Diaz, Jessica Simpson, Jennifer Love Hewitt, etc., recalled to the crowd. "She said something so honest to me. [She was] talking about the next opportunity, and she was upset about something, and she said, 'I just want people to love me.' And I thought it was so honest. Everybody should live like that. 'I just want people to love me.'"
