US Weekly : Jennifer Aniston, Jersey Shore, Sandra & Ryan and more….

Jennifer Aniston, this week’s cover of Us Weekly, and her beau of four months Justin Theroux are on the fast track to walk down the aisle…and procreate! As Aniston, 42, and Theroux (who turns 40 on Wednesday) kick back on an extended getaway in a $7,000-a-day cliffside compound in Kauai, Hawaii, the hot twosome have more on their minds then coconuts, cocktails and outdoor yoga. “They have talked at length about getting married and starting a family,” an insider close to the pair tells the new Us Weekly. “She is anxious for the next phase of her life and feels like this is the time.” And her hunky new guy (who split with girlfriend of 14 years Heidi Bivens in March) is completely on board with having a baby, a second insider says: “They both want it to happen soon.” To that end, health nut Aniston is making sure her body is in tip-top shape to conceive while on the island — hiring a private chef and doing at least 45 minutes of yoga daily. “She’s detoxifying,” an island source says. The Horrible Bosses star’s pals aren’t surprised in the slightest by Aniston’s race to become a mom with Theroux. “Jen hasn’t felt this way about anyone since Brad,” a pal says of Aniston’s ex-hubby Brad Pitt. (Aniston has had a famously rocky romantic life — with fizzled romances with Vince Vaughn, John Mayer and a slew of others — since her 2005 split with Pitt, 47.) Adds another friend: “They are moving quickly, but they know the feelings they have about [each other] are different from past romances.” Click here for the story!

Below are this week’s HOTSTUFF items about Ali Fedotowsky’s Wedding Worries, Neil Patrick Harris’ play date, Prince Harry’s R&R, Jessica Simpson getting carded and Emma Watson’s new boy… ALI FEDOTOWSKY Wedding Worries: No gym, no nuptials, says the bride-to-be Don’t expect a save-the-date anytime soon! A source tells Hot Stuff that Ali Fedotowsky does not regret recently delaying her wedding to Roberto Martinez. One reason: She needs to log some gym time first. “Since her knee surgery in July, she has not been able to work out,” says the insider. “She would like to be back in shape for the big day.” (Indeed, she told Us on August 2, “I don’t want to limp down the aisle!”) And though Fedotowsky, 26, could even need a second operation, she has other reasons for postponing her nuptials. The source says ABC — which will film the affair — offered up a December date for the duo, but she “doesn’t want her day overshadowed by [recent Bachelorette couple] Ashley Hebert and J.P. Rosenbaum. She really wants her wedding next summer.” Not that there’s any rush. As Fedotowsky tells Us, “I want to be married now. But in my mind, we are already married.” David & Neil Playdate in France! Neil Patrick Harris and David Burtka’s twins are only 10 months old, but they’ve already made some famous friends. On August 4, The Smurfs star, 38, and his business-owner beau, 36, along with tots Gideon and Harper, joined pals Elton John and David Furnish — and their 7-month old son, Zachary — on their yacht in St-Tropez, France. After the entire brood lunched at beach eatery Club 55, Harris tweeted, “The family and I are having one of the best weeks of our lives.” PRINCE HARRY Royal R&R! A vacation fit for a prince! On August 1, Prince Harry flew to the Mediterranean island of Majorca for a weeklong holiday with four pals. On their agenda: swimming, shopping, bar-hopping and boating — but no babes. (Harry’s latest London fling, British lingerie model Florence Brudenell- Bruce, was in nearby Ibiza, Spain.) After they landed, the redheaded royal, 26, drove himself (and his two security officers) to a luxurious villa in a rental car, and the gang hit the hot spots that night. “The guys shared a bottle of wine and a few beers” at Hotel Villa Italia, a witness tells Hot Stuff, then got another round at nearby Tim’s Bar. Two days later, the group rented boats to explore the coastline, and on August 4, they checked out a local beach. The rest of the time? Says the source, “They simply chilled at the villa and hung around the pool.” Jessica Gets Carded! Jessica Simpson’s fiancé, NFL player Eric Johnson, isn’t the only one who gets blocked! The singer, 31, was denied drinks after she couldn’t find her ID at Santa Barbara’s Bacara Resort & Spa July 27. Simpson kept her cool, a witness tells Hot Stuff, and “drank next door instead.” EMMA WATSON is working her magic on a new boy! The Harry Potter beauty, 21, was “very openly” smooching Perks of Being a Wallflower costar Johnny Simmons, 24, outside a Santa Monica eatery August 2, a witness tells Hot Stuff. Adds an insider on the set of Wallflower, shot this spring: “They had chemistry from the get-go. He didn’t try any moves. She just fell for him.”
