Birthday Lurve goes out to Ashlee Simpson-Wentz who celebrated her 25th birthday at Wet Republic at the MGM Grand Hotel and Casino in Las Vegas, NV yesterday. Joined by her hubby Pete Wentz, her older sister Jessica Simpson (not pictured) and a gaggle of her besties, Ashlee partied the day/night away poolside in the LV sun. Here are a few photos:

If you read the tabloids, you probably think Jessica Simpson is overweight and unable to stop crying and her sister, Ashlee Simpson-Wentz, is on the brink of divorce. Both sisters were at Wet Republic on Saturday and demonstrated that you really can’t believe everything you read in the tabloids: Jessica Simpson looked great and her little sister seemed to be very much in love. While supermarket rags claim the seniormost Simpson sister is distraught, insecure and overweight after losing both her boyfriend and her dog, the 29-year-old looked great and was all smiles at the MGM Grand yesterday. Still, supermarket tabloids suggest otherwise. Jessica Simpson was on the cover of Us Weekly last week. “Jessica falls to pieces,” the cover story announced, along with other details of her alleged “meltdown.” “Crying all the time, unable to lose weight and feeling alone, she tells friends she wants Tony back,” it claimed. A week earlier, In Touch ran what they claimed to me an “exclusive” cover story on Sept. 21 that called the singer “desperate.” “Jessica humiliates herself by reuniting with the man who betrayed her,” it charged. “Is she doing it because Nick is back with Vanessa and Tony’s flaunting a new blond girlfriend?” Furthering the attack, People.com ran a story on Sept. 21 declaring, “Friends Worry About Jessica Simpson’s ‘Tailspin’.” “After losing her beloved Maltipoo Daisy to a coyote attack, Jessica Simpson may be at the lowest point of her life,” the story began. The story quoted a source saying, “She won’t leave her parents’ house.” Yet Simpson was very much out of the house yesterday, and was dancing and singing along to the music as she made her way down the staircase to pose for the photographers who were waiting for her along Wet Republic’s blue carpet. Granted, dark sunglasses concealed her eyes and she declined to speak to reporters — but the blonde seemed to be in good spirits, despite it all. What’s more, contrary to stories that claim the singer has packed on the pounds since she and Dallas Cowboys quarterback Tony Romo went their separate ways, Simpson looked fit and fabulous in her high heels, a bikini and a stylish, sheer cover-up. Her sister, meanwhile, surprised pool partiers after posing alongside her sister, then retreating out of sight, only to return seconds later with husband Pete Wentz. Instead of having a girls’ weekend in Las Vegas, the Fall Out Boy rocker took a break from his tour to be with his wife on her birthday. So much for the couple wanting to take some time off. Yet Star Magazine suggested on Friday that the couple was definitely on the outs and hinted at a possible off-camera affair on the set of Simpson Wentz’s show. “Ashlee is giddy over Colin (Egglesfield),” Star said, and “her husband is jealous.” “The two have been fighting worse than ever,” the story claimed. The story cited a so-called “’Melrose’ set source” as saying, “On a few occasions, she broke down in sobs after angry phone calls.” Yet Egglesfield seemed to be the furthest thing from Simpson-Wentz’ mind yesterday; her real-life hubby was the only one she was being “overly flirty” with at MGM Grand. “I’m very happy in the moment I’m in,” she told the Sun. “My whole family’s here … the whole nine yards. It’s good to celebrate this with everyone.” In addition to her husband and big sister, her 10-month-old son, Bronx Mowgli; mother, Tina Simpson; and notorious father/manager, Joe Simpson, came to Las Vegas yesterday to mark her birthday. After what proved to be a whirlwind year, the petite brunette said she had a lot to celebrate. “I had such a great year … it was definitely the best year of my life, “ she said. “I had, you know, a child and got married.” She and Wentz tied the knot last May and welcomed their son in November. The young family traveled together and came to Las Vegas for the poolside birthday bash. “I came in today from tour, I’ve been on the road with my husband,” Simpson-Wentz said. The 25-year-old was only here for the day, but did her best “to relax and enjoy (her) friends and family” during the brief trip.

I have to say, I’m happy that Ashlee had herself a nice birthday and I’m also happy to see that reports of Jessica’s meltdown seem to have been greatly exaggerated. To be honest, it’s impossible for Jess to have suffered so much loss and not fall apart just a little bit … so it’s good to hear that she is getting out and moving on. I LOVE Ashlee on Melrose Place … she plays kooky/crazy Violet very well and I can’t wait to see what’s in store for that character. It sounds like Ashlee had herself a very nice birthday and that Jessica will live to see another day. Clearly it was a great weekend for the Simpson sisters!!
