No tabletop dancing, no outfit swaps and no walking around barefoot. Britney Spears — who turned 26 Sunday – celebrated her birthday at the Scandinavian Style Mansion in Bel Air on Saturday with cousin Alli Sims, pal Sam Lutfi and her back-on BFF Paris Hilton. The gang sang “Happy Birthday” as Spears blew out candles on a small chocolate birthday cake. Two enormous body guards shielded her table. It was a night to remember for the birthday girl, who scored $30,000 in leather and fur coats — including a $7,000 fur-trimmed white leather coat — at the gifting suites from high-end designer Katja Berglund. “She was very calm, nice, friendly,” Berglund said. “I know she's had some bad times here, but I think she looked really great.” After leaving around 12:45 a.m., Spears and crew continued the festivities at the Four Seasons in Beverly Hills. Hilton was spotted leaving at 3:50 a.m. Spears spent her actual birthday Sunday with sons Sean Preston, 2, and Jayden James, 14 months. Meanwhile, it seems Spears may have finally made a good decision. The train wreck, who hasn't done much publicity for her new album, "Blackout," besides her daily run to Starbucks to get photographed, has pulled the plug on a potential Rolling Stone cover, said an insider. Spears was close to signing a contract with editor and publisher Jann Wenner, to pose for the cover, but called off talks when the Wenner Media boss refused to promise her it would actually land on Rolling Stone instead of Us Weekly, said the insider. Last year, Nick Lachey was duped into believing Wenner's promise of a Rolling Stone cover and was furious when he landed on Us instead. "It was going to be a good platform for her music to be taken seriously because it had been so long. But she refused to get screwed by Wenner," said our source. "They kept negotiating, and it got nasty." Spears has contacted Blender magazine, and a deal is being worked out for a cover there, said the source. A rep for Rolling Stone said they were "exploring a cover" but never had a discussion about any kind of contract.
