If there was ever a time for Britney Spears to disappear for a while and regroup (we hear Greenland is nice right now), this is it. She's completed her month long stint in rehab, her divorce from Kevin Federline is final and her buzzed locks are quickly sprouting. But the paparazzi magnet mommy of Sean Preston, 18 months, and Jayden James, 6 months, doesn't seem all that interested in lying low. The bewigged and newly blue-eyed Brit's busy weekend not only included cheering on the Los Angeles Lakers on Friday and Sunday nights, but also traipsing to Las Vegas on Saturday for some retail therapy. "Britney and two girlfriends went shopping at the Forum Shops," a spy tells In Touch. "Everywhere she went, crowds followed her." And all that spending must have made Spears peckish because she and her pals popped by tony eatery Tao for dinner. According to the Las Vegas Review-Journal, Britney's minders asked for a table near the ladies' room "because she would be using the restroom a lot." Restaurant staffers were also supposedly told not to serve her any alcohol, although an eyewitness tells In Touch that she "looked happy and calm" while sipping iced tea.

Don't send that gravy boat to Brad Pitt and Angelina Jolie just yet (even if the attenuated Oscar winner could use the calories). The actor's rep is dismissing as hooey reports that the altruistic A-listers are looking to get hitched this month in the Dominican Republic. The nuptial nattering apparently began with a story in OK! magazine and grew louder last week after a local art dealer with ties to Pitt told the AP he'd received an email from the star inquiring about "marriage laws for foreigners." You'll recall that the prepossessing parents of Maddox, Pax, Zahara and Shiloh have made it clear they don't need no stinkin' piece of paper to prove their commitment. "Angie and I will consider tying the knot when everyone else in the country who wants to be married is legally able," Pitt told Esquire last September, a sentiment Jolie echoed in the December issue of Vogue, declaring, "We are legally bound to our children, not to each other, and I think that's the most important thing."

Ryan Gosling earned some serious boyfriend points this weekend. On Sunday, the oh-so-appealing "Notebook" thespian, 26, took time out from promoting his upcoming film "Fracture" to compliment Rachel McAdams, 28, his squeeze of two years. "She's kind," he told reporters of his "Notebook" amour (via People), who recently lauded the Oscar nominee's commitment to his craft in the pages of Elle, describing him as "very brave." "She doesn't need any help from me," gushed Gosling. "She's inspired me to do so much as well ... She's the most discerning person I've ever met. She'll read a script 100 times. She's relentless."

For a guy who parks his jets in the driveway of his massive Florida compound, John Travolta sure isn't shy about expressing his opinion on protecting the Earth. While stumping for the inexplicably successful "Wild Hogs" last week in London, he told reporters "everyone can do their bit" to lessen their impact on the environment, according to the London Daily Mail. At least the "Dianetics"-devoted gourmand, who zoomed down the red carpet at the London premiere on a Harley, acknowledges that he's "probably not the best candidate to ask about global warming because I fly jets," although he's quick to point out that he uses the pollution-emitting aircraft "as a business tool." Travolta even offers a solution to what he calls the "very valid issue" of global warming: "I'm wondering if we need to think about other planets and dome cities."
